Elaborating on a Flip ON Flop OFF circuit with a circuit that allows for a multi-state 10-position switch or a DAC.

The chip also provides a few neat tricks, like single-button on/off functionality ... A transistor and a few passives allow a SPST switch to act as an on/off switch: a short press turns the ...

The Raspberry Pi power switch provides a single button for both on and off just like most consumer electronic devices but can be wirelessly operated using the infrared remote control if desired.
