Abstract
Improved switching circuitry for use in connecting a remote control signal circuit to an electrically powered circuit wherein power for the remote control signal circuit is provided by the electrically powered circuit. Power metal-oxide-semiconductor field-effect transistors (MOS-FETs) are connected to a control signal output of the control signal circuit and provide the function of at least one diode of a full-wave rectifier bridge in the switching circuitry. The MOS-FETs respond to a logic 1 control signal to establish a low impedance path across the output of the full-wave rectifier that is connected to the electrically powered circuit.
