fan delay switch
OK, I've been on Google for an hour without success. I want a traditional looking toggle switch that will turn the bathroom fan on when flipped and turn it off automatically 15-20 minutes later. I'd strongly prefer it not have a "continuous on" position because it will invariably be flipped the wrong way and run for hours or days until someone notices. (the downside of a really quiet, remote bath fan) The fan and lights are switched separately, I don't want the fan to go on whenever the lights are turned on.
Does such a thing exist?
