I am usually all for repairing things myself if possible. But this? Ugh. I'm leaning towards a new mouse. One that is not Logitech because this is literally the FOURTH Logitech mouse in a row that has developed this issue. Replaced the switches in my G602 pretty easily. This looks like a freaking nightmare.
@@catch82 exactly, even I ever once switching my phone camera module by myself. but after seeing this video, I think i'd prefer buying another pair of it 😅
In case anybody is trying to fix the middle mouse button because it doesn't click anymore pay attention at 5:30. In between the springs you'll have to cut a slit open on that orange protective cover with an exacto knife so the little disk comes put. The disk is supposed to be dome shaped not flat. Just take a ball point pen and press into the disk until it looks dome shaped again. Not too much or else pressing down will feel too stiff. Wrap a narrow piece of electrical tape around the disk and board to seal and secure the disk. Thanks to the reddit guy that suggested this and this channel for showing us g604 users the path to repair.
Thank you for this video and the call out to Alex's detailed explanation. With your help, I replaced the switches in one of 3 G604s that all started having the double click issue. I had a little experience with soldering but this was the first time I de-soldered a component from a board. I like the feature set of the G604. It hits the sweet spot for connectivity and number of buttons. I initially bought two G604s for my desktop and laptop. First the desktop mouse started having the double click issue. The desktop gets more use in particular in MMO game play. Under warranty, I RMA'd that mouse at 6 months old. The replacement mouse failed after 3-4 months in the same way. Then the laptop mouse failed too. Very disappointed with Logitech for not using the right switches for the job. I've used Logitech mice exclusively since the late 90s and I was looking for an alternative when I came across your video.
I have 2 G604s, one of which is doing it on left click and the other on right click, I used to build microelectronics at work and this looks particularly brutal, but the 4 pack of switches is on the way.
the new optical switches should reduce the chance of double clicking, I have G604 and recently started double clicking on left click, I purchased a G502X Lightspeed just for the size and optical switches, maybe in the future I'll fix the G604 if it gets more serious, now it's 10+ times in 1000 clicks
Just wanted to leave some feedback. Thanks to your video I was able to take my mouse apart, fix the switches, and put it all back together properly. Great Video
I can not thank you enough for this detailed, clean video of the process. G604 is a wonderful mouse except it has this horrible, apparently "incurable" issue of double click. Almost a year back, I got mine replaced with new one under warranty but within 2 months the issue popped up again. It had been extremely frustrating. While searching for possibilities of replacing switches, I stumbled upon your video and got back some confidence that this mouse can be brought back to its senses. Finally got Japanese OMRON switches, replaced them myself, following your video. Now with new switches, the mouse is working just the way it is supposed to. I am so happy and relieved. Thanks again. Best wishes. :) :)
I did this repair with some new japanese OMRON from Aliexpress. The issue came back within 3 month. But thank you for the video! It was it very easy to follow along, without studying the whole device myself. Save me a lot of time :)
'Japanese' Omron switches... from China. Especially bought on a market place known for selling fakes and clones. It doesn't take a genius to figure out why the switch started to fail so quickly. 😉
⚠I may have fixed the issue** ⚠ Found reddit comments confirming that blowing compressed air into the button gaps fixed the issue. I don't have compressed air so just blew very hard into the gaps all around my faulty left mouse button. First time didn't work. Tried again this time with lips against the gaps of the button* , front, side and through middle button, both with and without left button pressed, and.... I've just been able to draw 50 lines in MS-paint with 0 gaps! previously 50% of lines would have 1 or more gaps shown. No idea how long this will last but I'm pretty pleased 🤞 Had same problem with 2x G602s and ended up just buying replacements. Hopefully this saves someone some money 💸 *Using a thin straw would probably be better. It would focus the air power and enable you to get into the crevices. **This ended up only being a temporary fix and it's getting worse by the day. I'm still going to try for warranty replacement. If they want me to post the mouse back to them I won't bother and will try switch replacement. This vid recommends Japanese Omrons, there's another vid at: watch?v=f3ZFqZbTnL4 with many other switch alternatives tested. ***No reply on warranty stuff yet so I decided to take the mouse apart. Was so much dust and hair inside. Scraped the contact areas of the gold switch thingy in the Omron just to remove any oxidization, brushed dust out of other areas, also cut a small square of cling film and put it over the switch to prevent dust getting in. I think Americans call it 'plastic wrap'. So far working perfectly in the MS-paint line test!! ****3 week update: still no double clicks since the above paragraph, so that completely fixed the issue. Might be no need for you to buy and solder new switches. Give it a try.
What a stupidly complex location for the switches. TOTALLY would've switches to other brand if they didn't have the lightspeed scroll wheel. Great video btw. 👍
I know right? This isn't my first time to change mouse OMRON switches but on every other mouse I have had to do this on I just remove the top cover and bam it's right there.
Thank you for this very helpful video. I just replaced both switches on my G604 with Japanese Omron switches. It's a pretty simple job if you know how to solder. I just had to buy some solder wick and a desolder pump. I had seen people use them in videos and never did it myself before, but it's very easy. Just take your time and follow the video. Cost: about 4$ for 2 switches, 12$ for a basic pump and some solder wick.
This sophisticated design seems to be a good way to implement the planned obsolescence. The easy fix for such an issue (in my case unexpected double-clicks) is a drop of silicone grease or so. I am using 5-56 and it works fine with most of the switches - can forget about the issue for a year at least. The only issue with this mouse in my zoo - it is very difficult to get there. The first G604 mouse I returned under the warranty. And the next issue happened a few months after the warranty was expired. So I got to fix it. But I did it with a syringe that time. A couple of years gone and it is sick again (along with the old M325 that is constructed in a way that much easier to access and lubricate her switch). This time I got the paperclip (peace of wire if you wish), sprayed a bit of 5-56 into a tiny cap, got some of the solution on the tip of the paperclip (that I slightly bent as a bow), and entered it into the gap between the left button and the housing from the front of the mouse towards the back. As it seen in the video from 4:00 to 4:05, the white switch button is situated somewhere in between the + symbol on the auxiliary button and the center of the wheel, so you got the idea where you have to poke the oily stuff. As long as there is a sufficient amount of the silicone grease on the top of that button it will find a way to get into the switch and lubricate/clean/cover the mechanism and contact points inside. I spent a few minutes poking and now back to work enjoying prompt response without unexpected double-clicks. I hope the Logitech company will change the way of manufacturing and would not celebrate the planned obsolescence, but will please the users with a long-lasting devices as it used to be in the beginning.
I do agreed it's way more complex than it needs to be. They could have easily saved money with less plastic and made the mouse lighter so I'm guessing there could be a reason for it. Maybe sturdiness? If there is planned obsolescence it would be the switches. I've more recently learned why these Omeron switches fail. Today's gaming mice are less tolerant to the electrical noise the switches have as they wear down. Logitech has more recently started to introduce optical switches which fixes the problem.
just to clarify your comment... you're suggesting to put a little bit of silicone grease onto the white switch button rather than replacing the switch? I have the same issue. took apart my mouse and I have the button available. I don't want to buy and solder another button if I can avoid that.
With your video I have finished the micro switch replacement of my G604 without any problem. I don't know if I can do it so smoothly without your video, since it's my first time to do such a thing. And this mouse is really complicated for its structure, I think. Thank you very much.
All right, so I did the entire disassembly and replaced the switches with Kaili 4 switches (which I really love...hopefully they last a lot longer than these Omron switches)...and I'm proud to say, I only have 1 extra screw. I did have to take a part a few times because the side buttons were not engaging and I couldn't figure out why...then noticed the white rubber covering has a corner cradle that had to be seated correctly or else it would move when putting back in the entire internal assembly. It's a pain, but I'm glad I did it myself.
Just filed a warranty claim because of this, but I'll keep this video saved for when it eventually happens again (as is expected with Logitech nowadays).
There are 3 main things wrong with this mouse: - double-click issue - rubber grips peeling off and falling apart - over-engineered af After about 2 years of use, my G604 is now having the double-click issue and its rubber shell is disintegrating (I don't have sweaty hands, if you should know). So, earlier today, I decided to take it apart. After struggling to get the outer shell off, I was greeted with the most complicated mouse internals. It's even more complicated than the already complicated G602 I also took apart before (it was also exhibiting the double-click issue). I gave up and decided to watch TH-cam videos of this mouse's teardown so here I am. 😅 I'll get back to it once the replacement switches arrive.
I love this mouse and I hate that Logitech discontinued this product. Now that I start having issues with it. I'm looking into repairing it. But seeing this. I know I have to find another product. I repaired a few smartphones and this looks way harder than that.🤔 Thank you for saving my time!
I have my MX510 and MX518 which are close to being 15-20 years old or so. After the heavy usage over the years they are as good as on day one. The left click in G604 on the other hand started to fail after medium usage, obviously shortly after the warranty has ran out. If not for that it would've been the perfect mouse, it has 6 buttons on the side which in the MMORPG I play are immensely convenient. I'll have to give it a go and try to replace them.
" After the heavy usage over the years they are as good as on day one." They are 100% not as good as they were on day one LOL. Fantastic mice though but use a new one and youll see.
@@Paultimate7 OK if we want to be picky, lets rephrase it :) MX510 after 15+ years of A LOT of clicking (work, FPS, RTS, MMORPG) no problems. G604 after couple of years of moderate usage - no-clicking/double-clicks
I RMA'd my old mouse that had right clicking issues. I just got a iFixit kit and decided to tear down the old mouse to see the switches with this video. If my new mouse craps the bed (which I assume what will happen) at least I'll have my old one torn down to replace the switches. Thanks for the video.
I owned G602 and really loved it over 6 years until the sensor stopped working. Then bought G603 and never a fan of its shape (feels too small compared to G602). When G604 came out I was so happy that it's a next-gen G602. However, it lost the ease of maintenance. G602 is so easy to dissemble. G604 however looks like a nightmare. The switch quality is getting worse, this is the 2nd G604 getting into double click issue (yes, last one was directly replaced by Logitech within warranty). G602 with much heavier use did not have this issue
Thank you for this. I went ahead and ordered the D2F-01F/Omron Japan switches from DigiKey and swapped out the bad ones. Ordered two extra just in case this happens in future. Not able to find an equal to G604 in my case...
You don't need replacement switches. If you just take the top part of the switches (can only be done on the left and right click switches), you can see the copper mechanical contact. Take that, clean the contact points with alcohol and put the switches back! Your buttons will work like new ones!!! You need Tweezers for this job
I tried and failed but thanks for your video, it saved me time. I damaged the printed circuit due to my poor skill, it's no longer solderable. Anyway, it was no longer under warranty. 2nd logitech dead with a double click problem after only a year or two, I'm done with this brand of scammers which doesn't care about its customers, moreover, the customer service is pitiful... For such expensive equipment it's shameful.
My g604 is currently having double clicking issues & watching this video makes me regret immensely about not buying a g502 back then instead. Seeing just how much of a nightmare it is just to get to the switches, putting it back together after all that sure is gonna be a worse pain in the ass.
I think you would still have experienced the double-click issue had you gotten a G502. Double-clicking is a pretty common issue with Logitech mice. I also had the issue on my G602 (and on my T-something model before that). My G604 is probably my last Logitech mice. I just replaced its switches and rubber. If it breaks again, I will be looking for a different brand.
When a mouse microswitch exhibits flakey clicks but still has decent mechanical clicking action then the contacts just need to be cleaned with contact cleaner such as Deoxit. I got my 4 Logitech Trackman Marble mice clicking properly again by using Deoxit on the offending switches. The microswitches in these things are half the size of switches in other mice and removing the top piece is quite difficult to do without breaking the tabs because the plastic is very hard and the fit tolerance between the top and bottom is tight. I also don't have a microscope to aid in this. At 55 the peepers ain't what they used to be.
You could introduce contact cleaner into the tiny gaps around the small actuator on top but that will be pretty tedious. I chose to get a pin vise (small handheld drill bit driver) and a 5/64" split point drill bit to drill a hole into one side of the top piece. The split point will help keep the bit from walking while trying to start the hole. Initially you need to apply good pressure on the bit just until a divot forms in the plastic. Then use only slight pressure after that or you risk suddenly poking through the cover and damaging the internals. You have to take this slowly and when you feel the drill bit grab a little it means you're about to pop through the side wall. This is where you need to hold back on the pin vise while turning to clear out the plastic "chips" from the inside of the hole and so that the bit doesn't crash into the internal parts.
The hole makes it much easier to introduce 3 or 4 drops of Deoxit into the switch. 3 or 4 drops is a lot for these switches but I wasn't confident one drop would be enough to make it to the contact points. It will easily wick into the hole. I only had a very small tube of it but it also comes in a plastic bottle that includes a thin needle applicator that would work better than the small tube I had. The Deoxit will start to wick out of all gaps on the switch. Just wipe off with tissue or paper towel.
Thanks for the video, i learned from you, but when i disassemble there is a very tiny Spring comes out, when the wheel disassemble step......where it should be ? i also didn't see from your video....... Please help to check for me and advise, Thanks~~~
Apparently it's not always de switch, since replacing didnt help me. After a certain firmware update things changed though. But a mat like you use is a must with this mouse, all those parts and screws can get annoying
As a person who used to solder boards practically every working day for a few years as part of my job. Not a bad technique. My only criticism is that you used far too much solder and i would have like to see you clean up the flux before starting to rebuild the mouse.
I was able to buy some springs that fit: 0.2mm wire diameter 1.5mm spring diameter 5mm spring length tho I think a 2mm spring diameter would fit better.
Thanks a lot for your tutorial, I just replaced the bad quality stock microswitches for the Kailh red successfully following your video because this mouse has tons of screws! Comparing the stock with the Kailhs, they are practically the same, nobody could notice the difference and the result is no more double clicks.
How are they holding up? Are they the same height and feel as the stock ones? I've seen some people saying they have to sand down some of these buttons or that they make the button a bit higher (not Kailh red though).
@@LLF1234 I installed 2xKailh red on one of mine. Didnt have any issues with their size. (they look identical to the original ones, except for color, sure). The other g604 was fixed by simply putting some wd-40 into the switch. One of my kailh sometimes does a double click, so ill be applying wd-40 to them too.
I haven't had any problems with my left and right clicks, but the middle click double and triple clicks. Recently it wouldn't even register some of my clicks... Does anyone know of a solution? Can the switch be replaced? If so, with what switch and how. I've had my mouse for almost 4 years and have been trying to find a replacement for over a year. All other mice I've tried are not as good as the G604. I don't want to pay $240 for a "new" G604. I can't believe they would discontinue the 604 without giving us a successor🙁
personally bind middle mouse button to the DPI down button and turn the DPI up button into a DPI cycle button instead. Did this day 1 since i never liked the MMB, but might be worth doing for those who have issues with it and don't want to do all of this.
I've been having connectivity issues where the light starts blinking and only the left click button fails to work, but all other buttons work. No idea how to fix it.
That thing is a total nightmare to work on, I am glad i bought a razer mamba 10+ years ago and replaced the switches once, 6 minutes to complete the swap (open, replace, close). I now just bought another razor with the gen3 light switches.
Hi there, I replaced my switch using your instructions and could put everything back together. All the buttons seem to work fine, but for some reasons, the sensor no longer tracks properly. The mouse becomes very laggy. Would you have any idea where I should start to tackle this problem?
Hey man, was wondering if you have an update on the switches. Are they still holding up? Also one more thing, as I am about to receive the switches in a couple of weeks and go through this operation as well, did you file the plunger height down or did you leave the as is? I've heard people say that filing the height a bit was better. Thanks for the video by the way, if it weren't for this I probably wouldn't have had the courage to attempt it :D
Hi, Thank you for your comment :) To answer your questions: 1. I have not had any issues with the mouse since switch change. 2. I did not file down the plunger height. The activation is a bit higher now but I guess it is a question of preference and comfort. Good luck with the replacement!
Re the plunger height, there's a couple of "crests" on the base of the switch that can be sanded down to reduce the total height - with my switches it was already done when I bought them. They worked really well.
I do not have all the gear to follow this switch switch, however I found this: DOUBLE CLICK ISSUE FIXED!!! Issue: Whenever you click once the mouse registers a double click. It causes problem to drag and click. FIX and EXPLANATION: This issue is caused by static electricity buildup inside your mouse (if the mouse isn't broken). To fix this, simply breathe into the gap between the mouse and the mouse button. Our breath has enough moisture to discharge the static electricity. This should help in removing the static electricity buildup. Generally when the environment is of low humidity or the buttons are clicked in rapid succession, static electricity tends to build up. This is a common problem in mouse since there's no other way for the static charge to be discharged. So I did blow in to the gap for a second or two, and for the last 5min it works fine, double switching gone. If it will return, cost nothing just to blow on it again :)
By any chance, do you remember the part number for the chinese switches you originally had on your G604? I'm not sure I should use D2F-F and D2F-01F due to them having 1A and 0.1A amp rating, respectively. Specifically for a G604, that is. Any issues so far since you've changed the switches to D2F-01F? Also, have you tried any 150gr switches like the D2F-01? I know it comes down to personal preference, but if you did, what were your thoughts? Loved the video. Thanks a lot for doing this!
Hello, I'm glad you enjoyed the video, thank you! To answer your questions, I unfortunately do not have access to the switches I took out of the G604. At a later time, if i come across them again, I will post the part numbers here. I have not had any problem with the mouse since the switch replacement. I have also not tried any other switches but the D2F-01F.
@@yogitech-3D I was just watching other mice reviews to take into account for any future purchases when I saw your notification. Thanks a lot! I'll stick with the G604 and get a couple D2F-01F switches.
i followed this video to fix my g604. it worked out well, but im still gonna do it again to switch from d2f-01f to d2f-01. meaning from 75gramm to 150gramm. the 01f feel too smooth for me, so they will trigger when i just rest my finger on them.
These Logitech mice became much more complex. I used to dissasemble G402 and re-solder the switches, but it took about 1 minute to take one apart. The G604 looks crazy inside. How are they even making any money on these?
n i had this problem i just opened up the OMRON switch, there is a tiny copper colored metal plate with a bend in it, over time this gets flattened by wear and tear and usage. I bended it back into position, closed everything up and done. it was faster than waiting for a shipment from the internet and it was free. :)
Been there, done that. Just have to be careful when bending to not make the switch to hard or too soft. Also have fixed the dome switch for the middle click by removing the thin orange film, reshaping the dome and carefully taping it back with regular clear packing tape.
This is my favourite mouse. I tried "fixing" the switch by opening and clean the metallic part like some videos, and i Broke it... Looks like soldering a new switch is easier. Going to buy another G604 and some switches
Well, all I wanted to do was take off the top and clean out the button, as I am sure the issue for me is it's clogged up with crumbs and/or animal hair. After seeing this video I am now willing to just buy a new one. Thank you.
I've got problems with my G604, and right now it's selling on Amazon for only $54.22 - delivered. I'll probably buy it with the insurance, because although these are great mice they are notoriously unreliable and develop several types of frustrating defects. Evidentially, Logitech knows about the defects, but they just keep producing the same defective circuitry (or software). Even Logitech tech support has no idea if the problems are software or hardware related, so it's still a crap shoot.
tbh no. Don't buy it. Or any Logitech mouse for that matter. Buy a properly designed one, where 50% of the design is not "how do we make it impossible to fix"
@@dansmith6909, 🤣 at the end I'm ended buying M720, where everything is easy to access and if the switch are failed i could just change the switch with even better and more durable switch.
I think this one lasted about the same or maybe even less time before double clicking vs the last 2 g602s i had. About a year. Pitiful. Ready to give up on logitech to be honest...
It seems they're going to make mice with optical switches, eliminating the mechanical debouncer (which mostly causes the double clicking issue). I just hope they add them to G604s too.
@@LLF1234 we can only hope. I tried a steelseries and after 3 months the scroll wheel started bugging out. You go up it will sometimes go down or not register at all... 😑
Wow, Now I see why they stopped making this mouse. I do phone repair for a living and have since about 2007 and this looks like it will be more complicated then more phone repairs. As a tip though get yourself an isesamo. Get an actual name brand one take some fine sane paper to the tip and sharpen it slightly. Having a good isesamo for opening things is beat by nothing.
8:23 If you're not an expert at soldering, then what does that make me? It took me an eternity to replace those switches and I burned one of my fingers in the process. Damn that iron is hot
I build drones for a hobby but this mouse is so complicated to take apart that it had me questioning the meaning of my life.
Most Logitech mouse look like a puzzle inside. And if there are space for 2 screws, logi never use 1.
The meaning of you r life was suggested by the mouse design - you do not have to fix it - you have to pay for the new one!!!
I am usually all for repairing things myself if possible. But this? Ugh. I'm leaning towards a new mouse. One that is not Logitech because this is literally the FOURTH Logitech mouse in a row that has developed this issue.

The g604 is the definition of over engineered.
In case anybody is trying to fix the middle mouse button because it doesn't click anymore pay attention at 5:30.

This sophisticated design seems to be a good way to implement the planned obsolescence.
The easy fix for such an issue (in my case unexpected double-clicks) is a drop of silicone grease or so. I am using 5-56 and it works fine with most of the switches - can forget about the issue for a year at least. The only issue with this mouse in my zoo - it is very difficult to get there. The first G604 mouse I returned under the warranty. And the next issue happened a few months after the warranty was expired. So I got to fix it. But I did it with a syringe that time. A couple of years gone and it is sick again (along with the old M325 that is constructed in a way that much easier to access and lubricate her switch).
This time I got the paperclip (peace of wire if you wish), sprayed a bit of 5-56 into a tiny cap, got some of the solution on the tip of the paperclip (that I slightly bent as a bow), and entered it into the gap between the left button and the housing from the front of the mouse towards the back. As it seen in the video from 4:00 to 4:05, the white switch button is situated somewhere in between the + symbol on the auxiliary button and the center of the wheel, so you got the idea where you have to poke the oily stuff. As long as there is a sufficient amount of the silicone grease on the top of that button it will find a way to get into the switch and lubricate/clean/cover the mechanism and contact points inside.
I spent a few minutes poking and now back to work enjoying prompt response without unexpected double-clicks.
I hope the Logitech company will change the way of manufacturing and would not celebrate the planned obsolescence, but will please the users with a long-lasting devices as it used to be in the beginning.
I do agreed it's way more complex than it needs to be. They could have easily saved money with less plastic and made the mouse lighter so I'm guessing there could be a reason for it. Maybe sturdiness? If there is planned obsolescence it would be the switches. I've more recently learned why these Omeron switches fail. Today's gaming mice are less tolerant to the electrical noise the switches have as they wear down. Logitech has more recently started to introduce optical switches which fixes the problem.
Back in the 90s my Logitech mice would work for 10 years. Today they work for ten months.
just to clarify your comment... you're suggesting to put a little bit of silicone grease onto the white switch button rather than replacing the switch? I have the same issue. took apart my mouse and I have the button available. I don't want to buy and solder another button if I can avoid that.
With your video I have finished the micro switch replacement of my G604 without any problem. I don't know if I can do it so smoothly without your video, since it's my first time to do such a thing. And this mouse is really complicated for its structure, I think. Thank you very much.
All right, so I did the entire disassembly and replaced the switches with Kaili 4 switches (which I really love...hopefully they last a lot longer than these Omron switches)...and I'm proud to say, I only have 1 extra screw. I did have to take a part a few times because the side buttons were not engaging and I couldn't figure out why...then noticed the white rubber covering has a corner cradle that had to be seated correctly or else it would move when putting back in the entire internal assembly. It's a pain, but I'm glad I did it myself.
Thanks! With your guide I was able to fix my double click issue. My first time soldering project was successful!
i just performed this repair as well. it would have taken several times longer without this video. thanks!
Your film is great, i ordered the switches and followed your film step by step and it worked and my mouse is as new again, thanks :)
just completed my G604's repair. Here's to hoping it lasts long enough for a proper successor to appear.
Just filed a warranty claim because of this, but I'll keep this video saved for when it eventually happens again (as is expected with Logitech nowadays).
Thank you! This video helped me complete the repair. I ended up with one extra screw. But, it seems to be working fine without it.
There are 3 main things wrong with this mouse:
- double-click issue
- rubber grips peeling off and falling apart
- over-engineered af
After about 2 years of use, my G604 is now having the double-click issue and its rubber shell is disintegrating (I don't have sweaty hands, if you should know).
So, earlier today, I decided to take it apart. After struggling to get the outer shell off, I was greeted with the most complicated mouse internals. It's even more complicated than the already complicated G602 I also took apart before (it was also exhibiting the double-click issue).
I gave up and decided to watch TH-cam videos of this mouse's teardown so here I am. 😅
I'll get back to it once the replacement switches arrive.
Great video man... I wish I was that capable and confident it looks scary...
I love this mouse and I hate that Logitech discontinued this product. Now that I start having issues with it. I'm looking into repairing it. But seeing this. I know I have to find another product. I repaired a few smartphones and this looks way harder than that.🤔
Thank you for saving my time!
This helped me realise that I will never attempt to swap them 😁. Great video
I have my MX510 and MX518 which are close to being 15-20 years old or so. After the heavy usage over the years they are as good as on day one.
The left click in G604 on the other hand started to fail after medium usage, obviously shortly after the warranty has ran out. If not for that it would've been the perfect mouse, it has 6 buttons on the side which in the MMORPG I play are immensely convenient.
I'll have to give it a go and try to replace them.
" After the heavy usage over the years they are as good as on day one." They are 100% not as good as they were on day one LOL. Fantastic mice though but use a new one and youll see.
@@Paultimate7 OK if we want to be picky, lets rephrase it :)
MX510 after 15+ years of A LOT of clicking (work, FPS, RTS, MMORPG) no problems.
G604 after couple of years of moderate usage - no-clicking/double-clicks
I RMA'd my old mouse that had right clicking issues. I just got a iFixit kit and decided to tear down the old mouse to see the switches with this video. If my new mouse craps the bed (which I assume what will happen) at least I'll have my old one torn down to replace the switches. Thanks for the video.
Thanks for this video, I managed to replace the switches, it was so complicated to take that mouse apart 🙂
What temperature is it for soldering? thank you
How many screw driver type to do all of this stuff?
What is the name of the small part at 4:21?
What do you call the soldering tip he used? It's like a fork or something
I owned G602 and really loved it over 6 years until the sensor stopped working. Then bought G603 and never a fan of its shape (feels too small compared to G602). When G604 came out I was so happy that it's a next-gen G602. However, it lost the ease of maintenance. G602 is so easy to dissemble. G604 however looks like a nightmare. The switch quality is getting worse, this is the 2nd G604 getting into double click issue (yes, last one was directly replaced by Logitech within warranty). G602 with much heavier use did not have this issue
I don't know. The MMB on G602 was a nightmare. I must've bought 6 of those 602s because the MMB kept breaking.
Any guide on replacing the 604 side buttons?
Which switches can i use for G4-G9?
Thank you for this. I went ahead and ordered the D2F-01F/Omron Japan switches from DigiKey and swapped out the bad ones. Ordered two extra just in case this happens in future. Not able to find an equal to G604 in my case...
Hinestly... I just use the heat gun and they came out easy lol. Works like a charm now, thank you got the video. 🙏🏽
Just did this fix! Thank you. My mouse is working correctly again.
is there a faster or easier way to clean a sticky left click?
Hi. I was thinking of replacing the switches of my G604 Lightspeed with Kailh silent mouse switches. Would those switches work on this mouse?
Did you happen to have issues with the middle mouse button not clicking after reassembly?
I just did a switch replacement on my G604 but somehow I gained 5 extra screws after reassembling...
Thank you!
Another G604 here that you helped to save :)
is it completly sold the double click issue ?
Do you have a link to the replacement Japanese switches? I've been frustrated by this same problem for a while now. Thank you in advance!
I have put some links in the description. See what's best for you depending on your region.
You don't need replacement switches. If you just take the top part of the switches (can only be done on the left and right click switches), you can see the copper mechanical contact. Take that, clean the contact points with alcohol and put the switches back! Your buttons will work like new ones!!!
You need Tweezers for this job
I tried and failed but thanks for your video, it saved me time. I damaged the printed circuit due to my poor skill, it's no longer solderable. Anyway, it was no longer under warranty. 2nd logitech dead with a double click problem after only a year or two, I'm done with this brand of scammers which doesn't care about its customers, moreover, the customer service is pitiful... For such expensive equipment it's shameful.
yeah....im just gonna get a different mouse. good on you for being patient.
thanks this guide helped me fix my g604 and its double clicking pita!!
This video inspired me to check if my mouse's warranty was still in date.
My g604 is currently having double clicking issues & watching this video makes me regret immensely about not buying a g502 back then instead. Seeing just how much of a nightmare it is just to get to the switches, putting it back together after all that sure is gonna be a worse pain in the ass.
I think you would still have experienced the double-click issue had you gotten a G502. Double-clicking is a pretty common issue with Logitech mice. I also had the issue on my G602 (and on my T-something model before that). My G604 is probably my last Logitech mice. I just replaced its switches and rubber. If it breaks again, I will be looking for a different brand.
hi,I would like to ask you, my G604 mouse also registers a double click instead of a single click. Is it possible that this component is defective?
When a mouse microswitch exhibits flakey clicks but still has decent mechanical clicking action then the contacts just need to be cleaned with contact cleaner such as Deoxit. I got my 4 Logitech Trackman Marble mice clicking properly again by using Deoxit on the offending switches. The microswitches in these things are half the size of switches in other mice and removing the top piece is quite difficult to do without breaking the tabs because the plastic is very hard and the fit tolerance between the top and bottom is tight. I also don't have a microscope to aid in this. At 55 the peepers ain't what they used to be.
You could introduce contact cleaner into the tiny gaps around the small actuator on top but that will be pretty tedious. I chose to get a pin vise (small handheld drill bit driver) and a 5/64" split point drill bit to drill a hole into one side of the top piece. The split point will help keep the bit from walking while trying to start the hole. Initially you need to apply good pressure on the bit just until a divot forms in the plastic. Then use only slight pressure after that or you risk suddenly poking through the cover and damaging the internals. You have to take this slowly and when you feel the drill bit grab a little it means you're about to pop through the side wall. This is where you need to hold back on the pin vise while turning to clear out the plastic "chips" from the inside of the hole and so that the bit doesn't crash into the internal parts.
The hole makes it much easier to introduce 3 or 4 drops of Deoxit into the switch. 3 or 4 drops is a lot for these switches but I wasn't confident one drop would be enough to make it to the contact points. It will easily wick into the hole. I only had a very small tube of it but it also comes in a plastic bottle that includes a thin needle applicator that would work better than the small tube I had. The Deoxit will start to wick out of all gaps on the switch. Just wipe off with tissue or paper towel.
Thanks for the video, i learned from you, but when i disassemble there is a very tiny Spring comes out, when the wheel disassemble step......where it should be ? i also didn't see from your video....... Please help to check for me and advise, Thanks~~~
OMG i found it , in your video 5:28.....
Apparently it's not always de switch, since replacing didnt help me.
After a certain firmware update things changed though.
But a mat like you use is a must with this mouse, all those parts and screws can get annoying
Did you do anything to fix it?
What a lot of work to get to the PCB, glad I have a space 604 so I can take my time.
Thanks for your great video!
Does the switch work for a G903 as well?
Looks like it does.
As far as I understand, all computer mice use the same type of switches, usually these Chinese Omron.
@@Crimzicgreat! Thank you very much for your answer!
As a person who used to solder boards practically every working day for a few years as part of my job.
Not a bad technique. My only criticism is that you used far too much solder and i would have like to see you clean up the flux before starting to rebuild the mouse.
I lost my springs XD, do you know the measurements of the spring?
I was able to buy some springs that fit:
0.2mm wire diameter
1.5mm spring diameter
5mm spring length
tho I think a 2mm spring diameter would fit better.
Thanks a lot for your tutorial, I just replaced the bad quality stock microswitches for the Kailh red successfully following your video because this mouse has tons of screws! Comparing the stock with the Kailhs, they are practically the same, nobody could notice the difference and the result is no more double clicks.
How are they holding up? Are they the same height and feel as the stock ones? I've seen some people saying they have to sand down some of these buttons or that they make the button a bit higher (not Kailh red though).
@@LLF1234 I installed 2xKailh red on one of mine. Didnt have any issues with their size. (they look identical to the original ones, except for color, sure). The other g604 was fixed by simply putting some wd-40 into the switch.
One of my kailh sometimes does a double click, so ill be applying wd-40 to them too.
is there anyway to reduce the behemoth weight ? i can find any on internet..
reddit
I haven't had any problems with my left and right clicks, but the middle click double and triple clicks. Recently it wouldn't even register some of my clicks... Does anyone know of a solution? Can the switch be replaced? If so, with what switch and how. I've had my mouse for almost 4 years and have been trying to find a replacement for over a year. All other mice I've tried are not as good as the G604. I don't want to pay $240 for a "new" G604. I can't believe they would discontinue the 604 without giving us a successor🙁
Amazing Tutorial. This helped me out a lot!!
Happy to hear it was useful. Thank you!
surprised mine lasted as long as it did. It broke last year and making the effort to fix it now
personally bind middle mouse button to the DPI down button and turn the DPI up button into a DPI cycle button instead. Did this day 1 since i never liked the MMB, but might be worth doing for those who have issues with it and don't want to do all of this.
I've been having connectivity issues where the light starts blinking and only the left click button fails to work, but all other buttons work. No idea how to fix it.
That thing is a total nightmare to work on, I am glad i bought a razer mamba 10+ years ago and replaced the switches once, 6 minutes to complete the swap (open, replace, close). I now just bought another razor with the gen3 light switches.
Great, i was wondering where those springs went.
😎Just blew air under the primary and secondary buttons as well as the side buttons, i have no compressed air, so I just used my lung. Works for me.
It helps me to fix my mouse at home! Thanks!
Hi there, I replaced my switch using your instructions and could put everything back together. All the buttons seem to work fine, but for some reasons, the sensor no longer tracks properly. The mouse becomes very laggy. Would you have any idea where I should start to tackle this problem?
Did you replace the sliding material under the mouse? if the sensor is just a tiny bit farther away from the table, it will misbehave. It did for me.
Hey man, was wondering if you have an update on the switches. Are they still holding up?
Also one more thing, as I am about to receive the switches in a couple of weeks and go through this operation as well, did you file the plunger height down or did you leave the as is? I've heard people say that filing the height a bit was better.
Thanks for the video by the way, if it weren't for this I probably wouldn't have had the courage to attempt it :D
Hi, Thank you for your comment :) To answer your questions:
1. I have not had any issues with the mouse since switch change.
2. I did not file down the plunger height. The activation is a bit higher now but I guess it is a question of preference and comfort.
Good luck with the replacement!
@@yogitech-3D thank you! :D
Re the plunger height, there's a couple of "crests" on the base of the switch that can be sanded down to reduce the total height - with my switches it was already done when I bought them.
They worked really well.
I have the same problem where do you source the new switch?
I got mine in a pack of 4 from amazon for ~$8
www.amazon.com/gp/product/B0062WNDLI/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
I have put some links in the description. See what's best for you depending on your region.
I do not have all the gear to follow this switch switch, however I found this:
DOUBLE CLICK ISSUE FIXED!!!
Issue: Whenever you click once the mouse registers a double click. It causes problem to drag and click.
FIX and EXPLANATION: This issue is caused by static electricity buildup inside your mouse (if the mouse isn't broken). To fix this, simply breathe into the gap between the mouse and the mouse button. Our breath has enough moisture to discharge the static electricity. This should help in removing the static electricity buildup. Generally when the environment is of low humidity or the buttons are clicked in rapid succession, static electricity tends to build up. This is a common problem in mouse since there's no other way for the static charge to be discharged.
So I did blow in to the gap for a second or two, and for the last 5min it works fine, double switching gone. If it will return, cost nothing just to blow on it again :)
Thanks, it helped! I was seconds from ordering new switches..
Where did you get the switches?
I have put some links in the description. See what's best for you depending on your region.
By any chance, do you remember the part number for the chinese switches you originally had on your G604?
I'm not sure I should use D2F-F and D2F-01F due to them having 1A and 0.1A amp rating, respectively. Specifically for a G604, that is.
Any issues so far since you've changed the switches to D2F-01F?
Also, have you tried any 150gr switches like the D2F-01? I know it comes down to personal preference, but if you did, what were your thoughts?
Loved the video. Thanks a lot for doing this!
Hello, I'm glad you enjoyed the video, thank you!
To answer your questions, I unfortunately do not have access to the switches I took out of the G604. At a later time, if i come across them again, I will post the part numbers here.
I have not had any problem with the mouse since the switch replacement. I have also not tried any other switches but the D2F-01F.
@@yogitech-3D I was just watching other mice reviews to take into account for any future purchases when I saw your notification.
Thanks a lot! I'll stick with the G604 and get a couple D2F-01F switches.
My G604 had the chinese D2FCF-7N(G1).
i followed this video to fix my g604. it worked out well, but im still gonna do it again to switch from d2f-01f to d2f-01. meaning from 75gramm to 150gramm. the 01f feel too smooth for me, so they will trigger when i just rest my finger on them.
These Logitech mice became much more complex. I used to dissasemble G402 and re-solder the switches, but it took about 1 minute to take one apart. The G604 looks crazy inside. How are they even making any money on these?
Salut! Vad ca esti din Romania , te bagi sa schimbi switch-urile si la mine? Daca da , ce cost? merci!
n i had this problem i just opened up the OMRON switch, there is a tiny copper colored metal plate with a bend in it, over time this gets flattened by wear and tear and usage. I bended it back into position, closed everything up and done. it was faster than waiting for a shipment from the internet and it was free. :)
Been there, done that. Just have to be careful when bending to not make the switch to hard or too soft. Also have fixed the dome switch for the middle click by removing the thin orange film, reshaping the dome and carefully taping it back with regular clear packing tape.
@@gheroba It's silly sometimes to see people throw away stuff and buy new ones when the fix is so easy.. ppl are lazy
i changed the swithces once, and now 9 month after i have to do it again. well.. at least i have tried it before... god bless logitech
This is my favourite mouse. I tried "fixing" the switch by opening and clean the metallic part like some videos, and i Broke it... Looks like soldering a new switch is easier. Going to buy another G604 and some switches
It's almost impossible to tell what exact screws you unscrew to take off particular part.
I wish my soldering skills can be as good as yours
disassemble this mouse is pain in the ass. i wont be able to put it back.
Thank you! left mouse switch replaced, works like new! Great Video!
Glad it helped!
forever thankfull of this video!!!!!
Zen - the art of logitech g604 care
So complex construction. I have disassembled few mice myself and usually you just take out few parts and have access to the PCB with switches.
i have a screw leftover? always the same with DIY
Thx for the help!
thanks i replaced the switch on my G604 by watching this video
Well, all I wanted to do was take off the top and clean out the button, as I am sure the issue for me is it's clogged up with crumbs and/or animal hair. After seeing this video I am now willing to just buy a new one. Thank you.
I've got problems with my G604, and right now it's selling on Amazon for only $54.22 - delivered. I'll probably buy it with the insurance, because although these are great mice they are notoriously unreliable and develop several types of frustrating defects. Evidentially, Logitech knows about the defects, but they just keep producing the same defective circuitry (or software). Even Logitech tech support has no idea if the problems are software or hardware related, so it's still a crap shoot.
looking this disassembly process makes me thinking whether or not I should buy this mouse 🤣.
BTW thanks for sharing. it is so helpful for me
tbh no. Don't buy it. Or any Logitech mouse for that matter. Buy a properly designed one, where 50% of the design is not "how do we make it impossible to fix"
@@dansmith6909, 🤣 at the end I'm ended buying M720, where everything is easy to access and if the switch are failed i could just change the switch with even better and more durable switch.
I think this one lasted about the same or maybe even less time before double clicking vs the last 2 g602s i had. About a year. Pitiful. Ready to give up on logitech to be honest...
It seems they're going to make mice with optical switches, eliminating the mechanical debouncer (which mostly causes the double clicking issue).
I just hope they add them to G604s too.
@@LLF1234 we can only hope. I tried a steelseries and after 3 months the scroll wheel started bugging out. You go up it will sometimes go down or not register at all... 😑
Wow, Now I see why they stopped making this mouse. I do phone repair for a living and have since about 2007 and this looks like it will be more complicated then more phone repairs.
As a tip though get yourself an isesamo. Get an actual name brand one take some fine sane paper to the tip and sharpen it slightly. Having a good isesamo for opening things is beat by nothing.
replaced mine with kaihl GM 8.0 switches, was time consuming but very easy
8:23 If you're not an expert at soldering, then what does that make me? It took me an eternity to replace those switches and I burned one of my fingers in the process. Damn that iron is hot
I've opened older logitech mouses and it wasn't even close to this complicated. they really went above and beyond to hide the switch.
That's just ridiculous. I figured it out and changed the big switches but... wow. There must be 50 screws in that thing.
Súper tu trabajo, pero realmente luce como una pesadilla desarmar ese mouse.
