Abstract
An energy efficient light switch providing dual switching capability for banks of overhead lights through the detection of infrared energy activity in a room. The switch has three positions preset by the user, activating a sufficient, but limited amount of light for a room through the automatic control of all, none or a portion of the banks of lights in the room. The switch is operable at 277 volts or 120 volts, has a sweep range of from 0.degree. to 180.degree. and is applicable for most lighting fixtures, fluorescent as well as incandescent and replaces the standard wall mounted wall switchplate. A method of manufacturing the energy efficient infrared light switch is also disclosed.
