A wireless transmitter associated with a switched electrical connection and a receiver therefor, adapted for connection in an electrical path between the source of power and a load, enables the load to be controlled by the switch originally used to control the switched electrical connection. The communication between the transmitter and receiver may be realized only when power is applied or removed from the switched connection, or, alternatively, this communication may be carried out on a per-cycle basis, enabling a phase-delay type of control over the relocated load, including dimming of the relocated load without requiring modification to a previously installed dimmer switch. The signal radiated by the transmitter may be of acoustic or electromagnetic origin, though IR transmissions are used in the preferred embodiment. The transmitter module includes means for making electrical contact to a switched electrical connection, and means for transmitting a wireless signal in response to the application of electrical Dower to the switched electrical connection, and the receiver module includes means for making electrical contact to a source of electrical power, means for making contact to an electrical load, and means for routing electrical power from the source to the load in response to the signal transmitted by the transmitter module. Exposed wires, plug- and socket-type connections may be utilized as alternatives depending upon physical implementation.
