Intermatic Incorporated manufactures timer switches designed for indoor and outdoor use. Many pool pump motors and water heaters use Intermatic timers to regulate their run times. An Intermatic timer-switch saves electricity when it turns a water heater off at night and when it limits the amount of time a pool's filtration system runs.
