A remote control receiver responds to a coded signal from a transmitter by actuating a switch that in turn acts to deliver power to a load or device connected to it. This switch responds not to one specific signal using a particular format, but instead it acts in response to any existing signal originating from any of a plurality of remote control transmitters. This switch, therefore, allows a remote control transmitter intended solely for activating and controlling a single device to control any such device provided the switch is attached to it in the manner disclosed.

A remote control infrared receiver for use with a remote control infrared transmitter characterized by a cyclic control signal in which each cycle includes a reader code and a user selectable variable custom and data code for actuating one of several possible functions in a first controlled device, comprising: memory circuit means for stretching the reader pulse code and shaper circuit means for converting said stretched pulse to an output signal; wherein said memory circuit means comprises capacitor charging means and capacitor discharge means driving said shaper circuit means, said discharge means having a discharge time greater than the interval between reader code pulses in successive cycles; and wherein said shaper circuit means comprises amplifier means for deriving a constant amplitude output of duration greater than the cycle time of said control signal; whereby said cyclic pulsed control signal is converted by said receiver to a constant amplitude pulse of minimum duration greater than said cycle time independently of the pulse coding content of the received signal; and switch means selectively responsive to a signal having said minimum duration.
