Simplest ON/OFF toggle switch circuit

In this video you will learn how to build a Simple DC Load Toggle Switch Circuit.
This circuit allows you to easily turn ON/OFF any DC load. You can also replace the bulb with a relay to control an AC load. The input voltage range is 0~45V, depending on your load.
How it Works:
Toggle Switch: The heart of the circuit is a a MOSFET switch.
Load: The load can be any DC device connected to the circuit. It could be a light bulb or any other DC-powered appliance.
Relay Option: If you want to control an AC load, you can replace the bulb with a relay. The relay acts as an electronic switch for AC devices.

Nice circuit idea. Especially, the supply voltage range. Even T flip-flops drain microamps in standby mode. Good thing to add a neat circuit diagram, a clear explanation & a pcb layout- very helpful to people with average electronics background! Make more videos of this type!

[@HobbyElectroLab]

Thanks for the support! Glad you enjoyed the circuit. I'll keep your suggestions in mind for future videos. Stay tuned!

This is the best toggle switch, you've beaten all circuits on the web. If you came up with this idea it's genius, if not please tell us the source. Thanks for sharing. This circuit requires 2 transistors, you can use P-ch and npn to power low side, and the best feature it doesn't oscillate when you keep pressing the switch.

Wow, thanks!

Amigo, montei o seu circuito aqui para controlar 4 reles comum de 12v em paralelo so que não dispara, so consegue disparar 1 rele se eu colocar outro em cima o circuito não liga. Sabe me dizer o que pode ser?

[@HobbyElectroLab]

Na verdade este circuito é apenas para 1 relé. Se você adicionar mais relés, terá que fazer algumas modificações no circuito. Não sei se você está adicionando relés em série ou em paralelo?

[@cafecomflores7274]

@@HobbyElectroLab em paralelo so coloquei o diodo na bobina de cada 1 deles. Mais estou adicionando 4 reles em paralelo. Qual modificação que eu tenho que fazer para que ele funcione?

[@HobbyElectroLab]

ok, no lugar de 4 relés, use apenas um relé com quatro números de contatos NF (normal fechado). vai funcionar bem.

[@cafecomflores7274]

@@HobbyElectroLab Não acho desses tipo de rele para comprar e preciso de contattos que suportem grande carga ~40A por isso que estou usando 4 em paralelo

Which transistor and mosfets can i use if i don't have irfz44 or A733?

[@HobbyElectroLab]

For T1, you can use any general purpose PNP transistors like 2N3906, 2N4403, BC556, BC327, BC157, BC558, 2SA1943, BD140, S8550, and For T2 you can try any general purpose N-Channel MOSFET like TQP 50N06, 55N06, IRF1404

[@xiaofang5096]

@@HobbyElectroLab thanks for response

[@claytondias1050]

Eu fiz esse circuito com com o Mosfet IRF510N e não funciona! O esquema é esse mesmo! O resistores e o transistor é são os mesmos, só o Mosfet que usei o IRF510N. O circuito fica sempre ligado, não sei o que seja, já simulei em um circuito virtual e funciona.

[@HobbyElectroLab]

Não entendo porque não funcionou, o IRF510N também é um MOSFET de canal N. tente confirmar se é normal

[@xiaofang5096]

se você replicar o esquema então deve funcionar, mas se você replicar o PCB mostrado neste vídeo então você também deve corrigir o erro no PCB conforme corrigido às 2:25 neste vídeo @claytondias1050

​@mikebond6328 Can I operate a 3kw geyser with 100 watt power source. It will certainly be a break through invention, for which even Edisson will feel proud of you. Well done!

[@HobbyElectroLab]

impossible.... or try it, if you can and let me know too.....

[@madhusudangupta3661]

​@HobbyElectroLab When you are already aware about the stupidity of the idea of your good self, why did you try to propose a cumbersome nonsense circuit instead using an innocent simple on / off switch.

[@HobbyElectroLab]

thanks for watching my videos. good job.

[@madhusudangupta3661]

​@HobbyElectroLab Sir, shame to you too.😊

[@lnglng6961]

❤❤❤

[@madhusudangupta3661]

A simple on off switch will do the same. No need of the circuit!

[@HobbyElectroLab]

You are right, but this circuit is designed for a push switch

[@mikebond6328]

With the circuit you can control a very large load with a very small amount of power.

[@HobbyElectroLab]

You mean, we can controll a larger load with small switch.@@mikebond6328
