Don't think it's particularly innovative really - a lot of electricians in the UK are now installing the Quinetic - https://www.quinetic.co.uk/ - system and it works really well in terms of wireless switches.

Mostly it's not to save the cost of the actual cable - but to save the install cost on an old brick building, where installing a new switch requires fairly extensive work to the house and brickwork.

I haven't seen Quinetic before. This is ever smarter than the solution in the article. Just use the kinetic energy of the press, rather than collecting ambient energy. Seems more reliable. OTOH limits what kind of switches can be used.

What sort of force is required to activate them, is touch enough? Do they make noise to click?

yeah exactly, I was like "what's new here?"

I already have these in my house
