Hi
I hope I'm not missing the obvious but is there such a thing as a push to close switch that returns when released. I have a extractor fan unit that has a humidity sensor and timer. The humidity sensor will take care of turning on when its needed to remove moisture so this is more for smells, I hate a fan being on when the light is on so I want a switch to trigger the fans internal timer but to auto release so it doesn't stay on if you forget to turn it off.
Cheers
John
