Thanks. There are plenty of on/off timers. I do not want to set times. I want the pump to be ON 24/7, and the I want to just walk up to it, turn a dial to 5 min, 20 min, whatever, and walk away knowing that in 5 or 20 or how ever many minutes later it will turn itself back on. In other words, a variable timed interrutor.
So this? Put it in a handy box and add pigtails.
