Soft touch power switch (Push on Hold off)

Michael Ruppe

Why people recommend it

Explains a push-on, hold-off soft power switch built from transistors with a readable schematic; recommended for battery projects that want one button for power and input.

In their words

This video here explains it well, has a good readable schematic, and is simply implemented:

Like this video of a power switch circuit, I used a current limiting resistor of 10K ohm between the button and the chip, relying on the protective diodes of the GPIO pin.

Does that mean a circuit such as described here ([video]) see 1:27m, would also not work, since the PWR_CTRL would have the same problem?
