It was definitely a complicated route to add an on/off switch. I ended up using a max6816 to " debounce" the switch and make it much more reliable.

The switch if of a standard vandal resistant type switch which you can find in most places.

Regarding the debouncer - A simple capacitor and schmitt trigger could have done it for a lot less in price - Case and wiring look nice though (silver wires a teeny bit overkill on pimeta? - or never too OTT?!)
