I'm looking for a push button with an integrated coil. Pushing the button would move a magnet inside the coil and therefore create a voltage.
I'm sure it exists somewhere because wireless light switches exist that don't require batteries nor wire connection. I'm just not sure if they are commercially available as single units.
I could build one with a small relay coil or similar, but it's kind of unprofessional. Has anyone seen something like this?
