Summarized by Shop
The Adafruit Push-button Power Switch is a tidy little design that lets you control a DC power source using an everyday tactile button.
The breakout uses a latching analog circuit that is triggered by a push of the button. Press once to turn on, then press again to turn off. The circuit uses a 3A P-FET to connect and disconnect the IN pin
