If you turn off your bathroom exhaust fan at the same time you turn off your bathroom light you probably aren't exhausting enough of the moisture out of the bathroom. The fan should generally be left on for at least 20 minutes after a bath or shower to insure all the moisture exhausted. This wall switch control makes it easy to run your bathroom exhaust fan correctly.
Connect your bathroom exhaust fan and your bathroom light to this switch (either a light integral with a fan/light fan or your regular bathroom light). Turn the switch on and both the lights and the fan will turn on. Turn the switch off the lights will turn off but the fan will continue to run (user settable up to 60 minutes). The adjustment screw is on the face of the wall switch, but will be behind the cover plate, so once you set it you won't have to think about it again. A cover plate is not included. The switch has a 2-position (“on” and “timed fan”) switch and is available in either white, almond (off-white), or ivory.
