About :

In this video we will make the circuit requested by some subscribers on the channel. Another approach to an on and off circuit, very step by step so that we understand all the concepts. The great advantage of this circuit (as with what we did with the two buttons) is that it does not consume power when at rest. It seems little, but many electronic circuits consume power even when at rest. ATTENTION: In the screen drawing the Mosfet is inverted. The Drain and Source are flipped. I am publishing the correct drawing on the Facebook page and right here on Youtube in the publications. This video is supported by JLCPCB, one of the largest and most respected PCB manufacturers in the world, but with a price that any hobbyist can buy.
