Lots of these sort of things use 'tactile' switches. My car remote
control does. And they all seem relatively short lived.
If they are pizeo, surely there's quite a high voltage to be dealt with
?
Not quite sure why they'd be 'pizeo'?

I saw an array of IoT crap at IBM a while back. "Kinetic" switches etc.
They were pizeo powered. Meaning you could stick them anywhere with no
need for wiring.
Ah - right. Didn't think of that. But wouldn't the push button move the
crystal mechanically to generate the power rather than being a switch?
