Soft latch on-off power switch

EEVblog #262 - World's Simplest Soft Latching Power Switch Circuit https://www.youtube.com/watch?v=Foc9R0dC2iI&t=795s&ab_channel=EEVblog This is Dave's concept, I just added a discharge resistor (10k) and two loads to see how much current can this circuit handle and a 100mohm resistor to monitor this current A short press on push button turns on the mosfet and a short press turns it off. If you press it for a longer time it will basculate. This circuit is ideal for controlling power on an Arduino board (Atmel328P for example) Feel free to play around with loads.... This circuit is a demand from Cameron1979 It's worth watching Dave's explanations on EEVblog ----------- I modified this with adding an n-mos transistor in my https://everycircuit.com/circuit/4609008530620416 ...'Soft latch on-off power switch.v2' circuit.
