Function

• Light switch timers activate lights inside the home automatically when you are not at home. They deter intruders by creating the impression that the house is occupied. Outdoor timers keep outdoor lights on while the house occupants are away or asleep, and can be programmed to switch on and off. According to the Burglary Prevention Council website, outdoor lighting "can provide valuable protection for the homeowner against intruders and can increase safety, while accenting the landscape."
  
  

Features

• Some light switch timers can be programmed to switch switch lights on and off at multiple times throughout the day, while others will switch lights on at night and turn them off at dawn. Timers may have dimmer functions to provide ambient lighting and conserve energy. Some security products control multiple home devices, including light switches.
