1. 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, said infrared proximity and remote control wall switch comprising:

  • a) 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;

    b) an infrared emitter for generating an infrared signal;

    c) an infrared receiver for receiving one of the infrared signal generated by the infrared emitter reflected by an object and an infrared signal generated by a remote control unit;

    d) means connected to said infrared receiver for filtering said signal received by said infrared receiver to eliminate noise signals therefrom, said means for filtering further including a counter and means for generating a reset signal to determine whether the received signal from said infrared receiver meets the minimum limitation of counts, a trigger signal being generated by said counter only when said received signal meets the minimum limitation of counts, and wherein said counter is periodically reset by said reset signal; and

    e) means connected to said means for filtering for connecting the fixture to the voltage source upon receipt of said trigger signal from said means for filtering.
