Great video! One of my POD GO footswitches had stopped working so I watched the 3:07 segment and then took the POD GO apart and injected some methylated spirits (It was 1am and I had no electrical contact cleaner in the house lol) with a syringe into the faulty microswitch and clicked the hell out of the switch button.
Reassembled POD GO and the switch works without fail now! Hurray for this informative video!
Nice!
Oh yeah, I've messed around with methylated spirits and a syringe at 1:00 am before. Now I attend meetings regularly. 😉
I too am repairing a guitar footswitch, bass actually. I was ready to scrap the thing. Boy am I glad I stumbled upon this video, and I was just looking for the talking dog!
Thank you, Viorel - even though your name sounds like it should be followed by "the gentle laxative..." (Man, am I a total TROLL or what? Vote me off the island!)
I was able to fix the 6 pins 8x8 mm self-locking DPDT push-pull switch. This switch is in my daughter's "Famosa Muak-Muak Bellies" toy that she put to swim, she was super happy I got it fixed! Thank you! 😊⭐⭐⭐⭐⭐
Nice! I'm glad she's happy again! You're a good father Pedro!
This is fiddly and time consuming but great to see that it can be done. I have repaired many synths and switches like these too. I feel the best approach is to replace them. If you look on line many of these things are available for the synth in question. In a lot of cases generic switches are used anyway. You just need a decent de-soldering iron though to get them off quickly and cleanly without damaging the PC tracks underneath. Brand new switches will always be better.
But with sliders for example, sometimes the slider is not available. But with care you can completely dismantle and clean all the moving parts of a slider and more often they will end up perfect again. But with a slider, if the carbon track is actually worn or missing sections then best to replace if you can get it. It is sill amazing how many parts are still available for vintage instruments too. You can take larger rotary pots apart too if you are careful and fully clean them inside and restore them to full operation.
Right! New is better..but when you don't have around, improvisation turns to art! About sliders, I repaired a double for volume with 2 mono side by side! Just a little plastic work in the case but still working after 10 years or so..Thanks!
I bought a whole set of these switches for my Sy99 even thow only one wasn't working. Weren't expensive at all. Now I just need to trust myself to do the repair. I will take the advice from someone else who said to take a picture as you take it apart so you will know how to put it back together. I've had to change the batteries which wasn't to hard to do, just nerve racking. One little mistake and it will be all over.
@@josephwazocha140 I replaced all the switches in a Korg DW8000. One of the best things I did was invest in a good quality desoldering iron. It really helps in a situation like this. Solderwick is probably OK if you are quick and clean about it. Often there are 4 pads per switch to desolder cleanly. Then it should come out easy.
@@josephwazocha140 'Learn the soldering technique on some old piece of electronics you don't need anymore. Try replacing the switches on that device first.
thanks to you my multitrackrecorder works like brand new, thanks alot
Nice!
Thank you so much, managed to fix my radio with your technique!
Glad to hear that!
The family has a Nokia 2720 Flip flip-phone. It is only 2 years old, but the side buttons have started to fail. The SMT micro-buttons on the circuit board are tiny compared to these vintage square ones. However, it was interesting to see you had some success with the contact spray, because these phone buttons are too small to easily swap out. For the benefit of anyone googling this here’s what I did:
Torx T5 screwdriver to remove the 4 screws. Guitar pick to prise off case assembly with tactile large buttons attached, revealing circuit board with actual SMT micro-buttons. A small drop of pure alcohol onto middle of a sewing needle, held sideways. Needle point moved down to the gap between metal switch housing and plastic moving part (actuator), then top of needle made vertical. Alcohol runs down needle into gap. Press actuator a dozen times soon after drop applied. Repeat for the other 3 side switches. Leave to dry, then reassemble.
This was not difficult, and seems to have 100% fixed the issue. Oddly, the problem was not of a poor contact but of too much contact - a more serious problem as it can lead to power drain, operation lag, incorrect operation and even failure to boot up (which all happened). No button could be seen sticking, so the issue may have been a piece of conductive material in the wrong place. Anyway this seems to have worked, saving having to buy a new phone!
Great job! Thanks for let us know. Nokia it's a great phone maker and worth any effort to save it.
Great, especially the method of un mounting an refitting the metal plate that holds the button in place.
It saved a lot of my vape mods. 90% of them get faulty over time, because vape juice seeps inside the switch. I alsoo use some hair spray when done, to seal them off and prolong the duration of the fix.
A littel bit of fat will help too..
@@viocaia don't know man. Vape mods can get pretty warm and I fear the fat would get liquefied.
Thanks for this video. This work needs patience!!
Glad it helped!
I've just had a similar problem on the CD eject button on my Ruark R4i audio system. Dousing it with sensor cleaning spray, that I bought for use on my car a few years ago but never used, solved the problem. I believe that the problem may have occurred because the CD player is rarely used, so the switch contacts may have just oxidised. OK, it might come back but I've now found that I can simply buy a new switch and replace it. Handy video, thanks.
Absolutely a new switch is preferable !
This was very helpful. Thank you!
Thank you too!
nice repair , the contact must be gold plated in the factory .
It should..probably to some other level
@@viocaia yes for military or space , i just ordered some button , cause the designer wired 4 button input to the same pin in the microcontrôleur with different resistor .
@@labiadh_chokri Nice..
Thankyou thats a great job ,very helpful .ive got faulty switch on washing machine . Ill give it a go .
Let us know the resuslts..
@@viocaia Worked perfectly thanks . I love your video .😊
@@myversionofstuff Nice!
Very helpful, thank you
Thank you for visit!
Thanks, it works. But I have a question, I cleaned some buttons with spray but one button I think I have the opposite problem, the button has a little resistance when it is open. How can I fix that?, I do not have the confidence to open it because my soldering iron is very bad and with the current quarantines it's hard to go anywhere.
Try to take out the metallic top..you need a sharp knife to cut those 4 little plastic dots, checthe inside, clean and retop, eventually just a top of crazy glue in each corner to keep the square metal in place..better with a soldering iron melt the corners a little to get tied to the plastic...of course a new it's always the best..
@@viocaia Thanks, I will try
very good info on these type of switches. And now i know how it works and how to improvise incase you dont have spare part around. Thanks a lot sir for the time involved in producing this video! Really appreciate it
Hope it helps!
Good info thanks
Glad to help!
OMG! Every one of those contacts would take so long! Would deoxit be helpful? I've never heard of siliconic fat but I'm going to look into it. Cool background tunes as well!
Any fat will do the job..it's just to keep the oxidation away..unfortunately there is no magic chemical to clean the contacts, mechanical is only way..of course new ones will be better, but I can tell you the fixed are here to last!
Great ideas well done
Glad you like them!
Very good and informative video
Thanks! Hope it helps..
Please explain how pushing the button closes the circuit. I cleaned the button but i still need to press very hard to make it work
Check the contacts, inside the case, there should like 3 ports, those need to be clean too
@@viocaia yes but why are there 3 contacts what is the purpose of each one of them?
@@ronenfe one in the middle makes contact when you press the wok like round piece, the sides contacts are necessary for the second pin, consider middle the first, to close the circuit we need to establish a connection between the sides touching the outer part of the wok and the middle touching evidently the fixed central contact. There are 2 sides for better functionality, those are in paralel, each touching the mobile wok disk permanently... 2 contacts at the edge are better then 1...
@@viocaia makes sense, you are saying the middle contact is connected to one side of the circuit and the two outer contacts are connected together already between them and connected to the other side of the circuit?
@@ronenfe yep, stay tuned, I'll do a video about tommorow
How long it works after a repair? My experience is afet a chemical cleaning the contact problem always returns after a few weeks.
Years! It's mechanical cleaning..if you add a little grease it will last forever
Thank you
You're welcome
nice video : i never tried to open them then ,clean the "rust/dust", and reassemble them !!
--> "Push Button 2 Pins 6*6*5mm" on aliexpress is 2 Euros for 100 pcs,
something that would help if ... time is not an issue for the repair
Thanks! Is not a matter of price..but what can you do when you don't have any? Take it like music..improvisation save the day!
@@viocaia fully Agree : took one month to get them on aliexpress ... that why if "time is not an issue for the repair" ;-)
i just tried alcool (24h bath ... with shaking sometimes) on the ones i had replaced yesterday by new ones : it worked on most unless for one that was locked (no push effect) : unfortunately they were not openable, so when "i distoyed it" to see what happened : some metal strip was locking it. -> "shaking" might not be a good idea after all :-D
@@SQueme Glad you could fix most of them, of course best way is replacement, but I found the new ones are just a piece of ordinary steel..prone to oxidation soon..I have a Ketron device like 15 years old, use to play day after day for years and still going like new..all the touches respond in a blink!.BTW..when you have funfixing something there is no more ''time''! Literary!
GOOD
Hope it's helpful
Isn't it easier and faster and more reliable to just replace the switches? They surely won't work as well as new ones after such brutal fixing. The sandpaper not only removed the oxidizer layer, but damaged the smooth surface of the contacts so they would deteriorate much faster now.
Of course, new is better! this is a solution when you don't have the parts, or you can't take the board out.Most of the time the switches are working for years..again.
I was thinking the same thing... _until_ I realized that I'd MUCH rather bust open the switches with my old pocket knife from Scouts, slather it in whatever household chemicals I have on hand (which turned out to be Dr. Pepper), sanded the $h;+ out of it until it was 5 microns -thick- thin, and then fry the delicate plastic case back into a somewhat recognizable shape with a charcoal brickette lighter (no soldering iron immediately handy). But that's just the kinda guy I am.
@@JamesDavisakaRemguy Sounds very skillful! Nice done!
@@viocaia You are simply fantastic, Mr. Viorel Caia! Thank God for you, sir! Thank you so much for your very helpful and earnest video, you have encouraged/inspired many of us to break open our defective electronic devices...and WADE IN - and be brave. Thank you, sincerely.
And I mean that, very seriously and truthfully. Despite my earlier shenanigans...
Why don't u just replace the switches 🥺

@@viocaia Sorry, my fault.
thank you!
I was able to fix GBA-SP trigger buttons (L & R).
Because I need fixed today, not after 3 months!
Nice!
Thanks to this video my bass pedal is now working again🙌 Had to pop the switch open, and tomorrow I’m going to take care of the other one.
Nice! Good work!
Thumbs up from a fellow bassist. This is gonna save me a lot of unnecessary trips to the "electronics only" section of the city dump. Boy, are they gonna miss me! (I hope)
i have one that is no longer clicky, but works fine still. what should I do? the tactile feel is important for this device of mine
You have to open or change the switch...probably that basculant piece lost the momentum.
Honest to god, why did I not see this earlier? I just bought a new battery charger as 2 of the buttons had died. Saw this, sprayed some WD40 contact cleaner, pressed the buttons a few hundred times and it works fine now. Thanks for the instruction!
Nice!
Wonderful tutorial. Thank you for creating this! What brand soldering pen are you using? Can you suggest one from Amazon? I'm tempted to get that multimeter too.
I'm currently using TS100 from MiniWare soldering pen. As for a multimeter, in the video I'm using an ''ancient'' M890G, but you can find better nowadays, from Kaiweets or any other. If you consider a purchase from Kaiweets please use the link and use the discount code VC10
There are plenty of TS like pens nowdays...you can go for SaintSmart TS101...
Is there another way of putting back the plate instead of welding it?
maybe a small drop of crazy glue...?or even safer hotglue all around
@@viocaia Ok. Thank you
@@daniko4447 Always
good video - but why using sandpaper to clean those tiny brass discs? Have you ever thought of dipping them in Coca Cola or vinegar? Coca cola cleans brass and copper coins easily it should do the same on those discs. Same for those contacts inside the switches - I'd use some balls of cotton dipped into Coca cola and leave them inside to do the job for you and wipe the lot a few hours later.
Never tried Coca Cola, seems a good idea.
You'll have to see by yourself to believe! I've used to clean brass bits from vintage saxophones - after a few hours I wipe the surface with some cotton buds - don't know about those micro switches but if the discs are made of brass or copper it should work.
@@stefanogortaldi3156 interesting, I've always thought this a folklore story
Thank you very much for this vidéo, i improvised with the first idea with alcohol, and repaired my zoom g2 pedal with same switches, idk if it will last but it's working for now thanks
Nice!
@Onyx Donald Nice to hear that!
Thank you for this. I just fixed a £5 head torch. The replacement microswitch would have been £2 and then soldering it nearly as much hassle as the WD40 and sand paper repair.
Nice!
fixed it
Nice!!
Cool. Thank you. I wonder what the contents of "contact spray" is. I have brake cleaner and acetone. The brake cleaner did not work.
The Swiss knife method is even cooler!
I think I have mended the switch that was broken in my "Toto Washlet" but I broke another switch that was not clicking well by breaking the pins in the PCB from the body of the switch when attempting to remove the top cover. I have some 4 pin switches on order. Hopefully it will be okay until they arrive.
Yes, it worked!
The non-functional switch (the off switch) now works.
The switch that I broke was to make the water jet weaker. Now the LED display says that the jet is on maximum power but that is how I like it so I may not even mend the switch t hat I broke.
BTW I am an English teacher
"inspire the air" >> "inhale the air" (or more colloquially "suck on the straw"
"time taking">>"time consuming"
And, I got some 2 pin micro-switches from aliexpress in the past, not that you need them.
Thanks! Nice you could fixed, I don't know what's the formula for kontakt spray..I believe some anti oxidant ..as for my english..well I never do a scenario before, I'm just shooting and talking..it;s hard to find the ''english'' expressions to the things or actions I'm doing..sorry!
Awesome!!! man!! its cool to see the patience and skill you used. A lot of people don't understand that skill of yours is learned from putting the time and effort into it. Also, its from tons of trial and error. Thanks a million for the lesson. i work on little small devices all the time. Oh by the way BICAGO's comment sucks. Hes just don"t have the skill man!! I bet you know what i mean. Good job.
I really appreciate your comment! TH-cam should be a way to learn and help each other.Be sure if I will find some new tricks ..it will be here.I found that the most of the'' heaters'' are professionals (suppose to be) ! Thanks again man..and BTW look at my last video about recovering a XLR connector..it should be crazy to do something like that..but why not if it's fun...and save money!
@@viocaia Right man! My friends always ask me the same question over and over? They ask" Why didn't you just by that part. Its only $5 to $10 bucks. I answer the same way to all " i enjoy saving the money and make these little devices cause i can. To be able to just do it is worth more than the money.

What kind if silicone you put inside of that tac ?
It's not really necessary, but you can use any light silicone grease, mostly to prevent oxidation.

Have you ever tried an ultrasonic cleaner?
Nope, but it feels ok..
@@viocaia Hmm, I'm not sure you meant that quite in the manner it would appear. But...it's funny! Full points.
Great video! I used this to fix the broken switch on my daughters ‘play kitchen’. Now she can hear bubbles again when she pushes the “cook” button 😊
Beautiful! Two happy people..three including me! Thanks! :-)
That is time consuming job. These switches are available everywhere and used good ones that be found on TV sets and CD players.
Of course..I did that because it's difficult to take the switches out from an old board, without burning it with hot air station or a hot iron..just trying to keep it simple..Time is not a problem when you have fun!
@@viocaia you can de solder them out without using heat and it will surely be less time consuming.
@@waleed9128 I'll try that next time! Thanks for advice..
@@waleed9128 How do you "desolder them out without using heat" exactly?
@@ShallRemainUnknown by using a solder wick and a solder iron, the old fashion way.
Don’t waste your time with this. I just spent several hours following this video and wasn’t successful. The problems I had were that when you pry off the metal top,it becomes mis-shapen and is too small to bend back to its flat shape. Also, the tiny round disc lost its dome shape when I sanded it. This meant that the button wouldn’t pop up and down properly. These parts are so small that there’s a good chance you’ll lose one in the process. Save yourself a lot of time and frustration and just replace the switches.
@@viocaia Time spent mastering this “skill” is certainly time wasted, given that it’s an imperfect solution.
