I'm pretty sure it was somewhere on here but I can't seem to find it:
Thread was about a timer switch, like those used for heat lamps in a bathroom. It was reverse wired so that instead of staying on for a certain amount of time, it would do a timed shut off, so you could shut off a pump for an overflow or filter and wouldn't have to worry about forgetting to turn the pump back on, as it would come on when the timer went to zero.
Sound familiar to anyone?
