Abstract
An infrared proximity and remote control wall switch positioned between a fixture and a voltage source for allowing a fixture to operate in one of a manual and automatic mode. The infrared proximity and remote control wall switch includes a three position switch operable between a first on position connecting the fixture directly to the voltage source, a second off position for disconnecting the fixture from the voltage source and a third auto position for allowing automatic operation of the fixture. An infrared emitter generates an infrared signal and an infrared receiver is connected to receive one of the infrared signal generated by the infrared emitter and reflected by an object and an infrared signal generated by a conventional television, video cassette recorder or hi-fi remote control unit. A device is connected to the infrared receiver for filtering the signal received by said infrared receiver and eliminate noise signals therefrom. Connected to the filtering device acts to connect the fixture to the voltage source upon receipt of a filtered signal from the filtering device. This device is able to eliminate noise signals from affecting the operation of the fixture when the switch is in the auto position and is able to activate the fixture to turn on at a plurality of different intensities. A timer may also be included for turning the fixture off after a predetermined period of time has passed since activation.
