Please log in for more thread options 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: http://www.rewci.com/fandetisw.html 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. Laura | ||||||||||||||||

> ... perhaps a VERY big smell? > Bathroom fan should be continuous, like the fan on a CPU. NBD Since the time man has done his business in the space where he lives, the stench will not leave w/o 24/7 exhaust. | ||||||||||||||||

Might take a bit of mechanical work to install but shouldn't be too hard. http://www.bgmicro.com/index.asp?PageAction=VIEWPROD&ProdID=11333 http://www.bgmicro.com/index.asp?PageAction=VIEWPROD&ProdID=12340 http://www.sciplus.com/singleItem.cfm?terms=12231&cartLogFrom=Search http://www.surpluscenter.com/item.asp?UID=2007090512144066&item=1-1614&catname= Cheers!!!! ============== Dave M Never take a laxative and a sleeping pill at the same time!! | ||||||||||||||||
