I'm looking for a delay switch for a bathroom fan and I haven't found any that have exactly what I want -
- adjustable time interval from a few minutes to, say, 1/2 hour. I'd rather not get one that just has a few choices for time interval. You can get one that gives you 5,10,15, 30 or on-until-switched-off choices, but I'd like to have it completely adjustable.
- time delay interval controllable on the outside of the faceplate
- doesn't make noise. Spring timers all click as I've heard, so not a spring timr.
What the delay switch does, is you can leave the fan on after you leave the bathroom, for an adjustable time.
The closest thing I've found is this:
It has a delay of up to an hour. I don't know why anybody would want to keep the fan on in the bathroom for an entire hour after leaving, but I guess it's conceivable. So I'd live with that.
But it's designed so the time delay adjustment is hidden behind the faceplate, and changed with a screwdriver. I want to have the delay adjustment on top of the faceplate. So there would be a sort of screwdriver blade attached to a knob, anchored to the faceplate somehow.
Any ideas about how to do this, so it would work reliably?
Alternatively, I'm sure it's possible to get a circuit that will do the delay function. If the guts of it could be covered over so it looks nice
- I could buy a wood faceplate and cut circular holes in it for the knobs - that would also do. It would have to fit in a gang box, or whatever they call the metal box that switches are enclosed in.
