Programmable wall switch timers are commonly used for automatically turning appliances off and on, such as lights, heaters and irrigation systems. Programmable wall switch timers are also useful for bathroom vent fans and motion detector systems.
Programmable wall switch timers work for both indoor and outdoor motion detector lights. They are also used for turning on lights for a preset amount of time in certain areas. This is useful in rooms in which only a small amount of time is spent, like closets and attics.
Another use of programmable wall switch timers is for turning on sprinkler systems. Sprinkler timers may then be used to water the lawn when no one is home or in the early morning hours.
