Thanks for the links, I didn't see the hackaday post. Half-bakery is fun but also a bit depressing :-) The point about the self-actuating switches is to make them as close as possible to a conventional switch, for the spouse-acceptance-factor. Also I really hate "tap buttons" for light switches. The next step would be a dimmer, not a using a flimsy rotary encoder (that turns around infinitely and reacts slowly) but an actual potentiometer that moves when you change it remotely. There are such potis in high end studio equipment. I think this idea actually has merit and there is a market for premium haptic interfaces, for example in cars. But it is hard to make a MVP and get a foot in.
