ABSTRACT:
A remote control apparatus in which a plurality of loads, assigned to a plurality of load stations, can be individually addressed via a single signal line without the use of complex multiplexing and demultiplexing circuitry. A pulse generator outputs bursts of pulses of a predetermined width onto a single signal line which interconnects all load stations. Each load in the system corresponds to a single respective one of the pulses of the burst. Each load station includes a switching device for selectively shortening selected ones of the pulses. Each load is activated in dependence upon the width of its corresponding pulse.
