In this video, i will show how can make a touch switch that is gonna replace the normal switch with the help of mosfet transistor.We will make a mosfet button that operates when you touch your finger to the terminal of the transistor.This type of switch can be made with regular transistors but connected in a Darlington pair multiply the number of transistors and amplifying the gain.
The metal-oxide-semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET). It has an insulated gate, whose voltage determines the conductivity of the device. This ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. A metal-insulator-semiconductor field-effect transistor or MISFET is a term almost synonymous with MOSFET. Another synonym is IGFET for insulated-gate field-effect transistor.

Hi there friends the new video is here ELECTRIC :th-cam.com/video/62cCYDpGV8o/w-d-xo.html
i like the excitement with which you are explaining. Loved the video :)
hari bukke Prasad Thanks I'm glad you like it. all the best and stay tunned
Mosfets are awesome! Great video.
MJ Snosk8er thanks buddy check out my other videos about mosfet you can make lots of stuff with them all the best and keep experimenting
very simple project and explanation nice bro!
Filazy Arubazy thanks bro enjoy and use as you please I will make a better version soon
Love the MOSFET🥰😍🥰😍😍😍🥰😍
love it man....
.
i am thinking that why you haven't much subscribers
School projects LAB Thanks mate nobody cares about real useful staff I have lots of ideas but not enough money or time to give them all free to the world but I am trying all the best
Light automatically turns on after sometime for me any solutions??
I found what I need for my project! Thank you! I followed u now!
Glad that i can help all the best my friend
Bravo!!! mai vad si romani care sunt interesati de electronica.
Gabriel Neculaica Thanks buddy Romania a great country with lots of inventors and talented peoples all the best
HI Sir.
what if i wanted to use this "switch" to turn on-off my FM radio project?
The FM radio work on a 3.7v Lithium battery and an amplier (lm7052 same 3.7 v source) :-)
Attila Rivera will work as long as the power source is less then the mosfet can support watch the other videos lots of info
Very Very Good
Kumar V Thanks I hope you find it useful if you want to be notified of new projects subscribe all the best
please reply do you have any where it is just the mosfet the probe 1 resistor and the switching terminal?
very very nice projects
Ariz Muhammad S. Salih Sumra Thanks check the new touch switch it looks so real all the best
Can you make it simpler such that it's a momentary switch that the light goes off when your finger is not touching the contact point?
Cosmo John I think you can add a capacitor or check out the new video capacitive touch...
Maybe even using transistor instead of the mosfet, when you touch it connect + with resistor to the base pin and it works when you remove the finger it turns off. Or if you need a mosfet because of the big load, you just add pull down resistor on the ON switch it will drain remaining charge and mosfet will turn off the time you remove the finger off of the switch.
Nice circuit
Thanks, buddy check out this new one looks more commercial th-cam.com/video/8voKWgZB7_4/w-d-xo.html all the best
Sir you are our proud
+salman noor Thanks buddy I do my best to teach others what I did learn through the years of experimenting all the best and I noted your request
Very good...
This can be use for security alarm device..
Thanks useful and easy to make all the best
When I try this , the light automatically turning on ( slowly increasing the the voltage across led ) even after I turn-off with touch . Don't know why , need help
great video
Will it works on home appliances?
Mobin Ahmed combined with a 120/220v relay yes as it is just an led or small radio or something similar
Hi, Nice Video ,
I want a button like door bell button which is to be operated by touch
And I want to use it on my cars horn cos when I drive smoothly , I need to apply very much pressure to honk (atleast in Indian XUV 5oo)
So if I can intall like this anything please suggest or make video of
'how to make your car horn touch '
I am sure this will boom.
No car provides touch horn
Thanks in advance
Bhanu Vashishtha thanks my friend I will sure do one I did found some comercial and cheap touch switches soon buddy stai tunned
@@NoSkillsRequired thanks ,
beautiful
the whole point is to NOT touch metal, i.e. risk of shock. in electrical appliances, also this has no static shock protection
Just a proof of concept using body internal resistance
In the video you are using one switch, can you make a video with a "2 way switch" ? TY
pici24 this is a simple switch converter in a touch switch but being 100% realistic is not a true touch is a cheap diy way. Real touch has a micro controller that store a value and compare that with the previous if is on or off
@@NoSkillsRequired Well..it is working and only that matters! :) Can this setup hold for fast/verry fast on-off operations ? something like "many" hertz .. thank you for your answer ! :)
pici24 ir may work I tryed with rapid switch by hand try and you will see these mosfet are not that expensive
@@NoSkillsRequired This I'm planning ! :D Thank you verry much for the info and for the video..keep up the good work !! :) PS only N mosfets are working or any mosfet is just fine ?
pici24 n channel mosfet different mosfet different specifications this is tested as you can see in the video all the best with your projects glad to be able to help
👏Very good👍like👍
cristiano Giatti thanks buddy can be useful in some cases and very easy all the best
can i use in 220 volts
SANDEEP DHIMAN I have a video showing how to use this for 220v all the best
That doesn't answer my question about what milliamps at 4v to feed to the gate so I can calculate what resistor I need to reduce 50v to 4v so I can then add a variable resistor to the circuit so I can regulate the output of a DC generator I made without turning the motor gas idle down so I can leave it at a good RPM with a 50v 40amp output from the DC generator head going to a variable voltage regulator
Dalton Neumann I don't get it what you need to reduce 50v to 4v?so you have a generator that outputs 50v at 40a or similar... and you need a switch or you need something to reduce the amperage?
@@NoSkillsRequired I just need to know how many milliamps the gate of the z44n takes or draws. so I can use oms law to calculate what resistor I need going from the gate to the source pin or ground so im not feeding the gate 50v and busting the mosfet by doing so.so I need 4v to the gate with a 50k potentiometer switch use it for variable voltage regulator for my diy generator. I know the gate takes 2-4v to turn on with a Max of 20v input to the gate .that's why I need to know how many milliamp the gate needs for my calculation. Please let me know the milliamp draw of the gate it's the only variable I need for my calculation. And thanks again for the help
Ok I found it if you ever need to know it's around the gate amp draw at 4.8v is 0.000171amps thanks for the talk and the help got to get back to working on it. I need a 250 k,ohm resistor with a 50k ohm variable resistor iv been set back three days on this it's good to be moving forward with it thanks again 😊
Dalton Neumann nice one I am glad that you find it good luck with your projects keep in touch
@@NoSkillsRequired thanks again and I will
I just thought it was fantastic. But I was curious: would it be possible to activate the light with just the touch of one hand without having to touch the other hand at the same time? Thank you
Is just one hand switch that was the demonstration
I like it.
Jibiram Areekaravalapil Thanks
Can I use it for a motor about12 or 24 volt
it depends on the motor what is the power of the motor,if you have the same mosfet there is a video mosfet irfz44n datasheet check there to see the ratings,also there is another way to use a 12/24 relay controlled by this touch switch in this way you will dont have to worry about heating and other problems search it on my channel touch switch 220v relay
How to use it in 240v ac power supply with a relay or without relay for switching on/ off
Singh Sandeep here you go my friend th-cam.com/video/qvrjrWzR6wM/w-d-xo.html the principle in how to use a relay and this touch hope to hear from you again
You should have told names of those pins,anyone can easily confuse between gate,source and drain
paritosh pandey there is all the information needed you can't find easyer the this my friend all the best
good but it needs two resistance to make it work , I'm looking for a one touch On OFF = just one finger touch
Edifier Bass hi there search for capacitive switch I have something in plan but the diagram is a little more complicated stay tuned all the best
OK thank you so much
Edifier Bass no problem any time friend all the best
How to use this trick in induction cook top
.send me the link
Did it work with 3.7v?
😙👌
Sir also in pakistan there is low voltage we making regulator stablizr etc sir can you do softawre to ic sir
+salman noor arduino is the closest that I get to program an ic
Like
Mohamed Twkl thanks enjoy
Do you know where I can buy a mosfet?
Ebay,amazon,aliexpress all electronic sites or you can salvage one from old electronics like tv,pc power supply normally any electronics that have a power supply greater than 12v dc. Check the video description you have an amazon link all the best
Ca i use this for 220 VAC..? If not what shall i use? thank you very much...
+Rey De guzman nope în order to use the same principle on 240/120v you will need a mains relay all the best
NoSkillsRequired thank you so much for your info...
Rey De guzman no probs buddy any time
Merry Christmas everyone
Thanks enjoy the rest of the videos all the best
how can we apply this to higher voltage 220v?
hi there my friend you can do it with a relay and connected to 240v
can we use any monsfets
+Ricky Baruah I think so try it first should be ok. This is a common mosfet irfz44n
Any MOSFET can be used ?
Wayne197732 Taylor I think so in this video is Irfz44n test it and let us know all the best
Very gooooood 😍
Thanks check out the new video better touch pads
Sir you are very able and intelegent that.s way i ask a question from you and now also you are our teacher sir i have ic lm 358 there is 8 pin sir but i dont know the input pin out pin
+salman noor ok I will start researching
Where are u from any imo id
+salman noor I'm from UK but was born in Italy you can find me on Facebook, Twitter and instructables.Com link in video u?
Música brasileira samba??????
Yes this is it nice one.All the best
Please which no. Of MOSFET no.

Can we use 75nf75 fet
salman noor if is a nchannel mosfet yes all the best
salman noor Yes 75nf is a nchannel mosfet so can be used like in the video
so basically sir, all nchannel type mosfet can be use for this project?
xtian de castro Yes all nchannel mosfet can be used in this configuration but you have to look at your mosfet drain to source voltage not exceed that and you are good to go
okei sir, thanks alot!!!
Sir and also understand us the other purpose of fet
Hi there check out the channel i have project on audio amplifier,inverter and touch switch with the same mosfet
NoSkillsRequired sir this will be very nice sir
Twenty eighteen.
+TheDestroyerTown 2018 will have face recognition switch 😂
ammata ukapan
Sir you are very nice good we wil waiting for your new vedio
salman noor Thanks stay tuned subscribe and share this video the 220v touch switch will be in 2days all the best
Can i used it for li-ion battery? 3,7volt
+TIRTA GT yes sure with li ion I tested the circuit
very good, but explain which source or drain and gate not only pin thanks.
Thanks you so much bro
+MD ayub khan No probs I am glad that you find it useful don't be a stranger subscribe all the best
This is prone to sporadically being triggered due to ESD. A better choice would be to use an IC that specifically handles touch.
+damny0utoobe This project was ment to be easy for everyone to understand what a mosfet is and it's uses. Happy holidays
+damny0utoobe Nope it uses the body resistance to charge and discharge the gate of the mosfet.......No ESD involved
