A system for supplying power to and switching a number of electrical appliances each having a power consuming part and a switching part, each switching part having a unique address. A signal line is coupled to each of the switching parts, to a clock pulse generator and to individual signal transmitters, each transmitter corresponding to one switching part, for generating a control signal for addressing its corresponding switching part. The signal transmitters, when activated, generate a characteristic control signal in synchronism with the clock pulses from the clock pulse generator. No central encoder is required for controlling the individual electrical appliances. Rather, it is necessary only to activate the particular signal transmitter associated with the particular appliance.

A system for supplying power to and switching electrical appliances, each of which has a functional power-consuming part and a switching part, comprising: a power conductor connected to a power source and to the power consuming part of each of said appliances; a clock pulse generator for generating a clock pulse signal; signal transmitters for generating control signals for addressing the switching parts of said appliances, each transmitter generating when activated, a characteristic control signal that is a predetermined function of the clock pulse signal; a signal conductor connecting all of said transmitters and switching parts, each of the transmitters and switching parts including a signal part which is structured so as to be configureable by manipulation thereof either as a signal generating part in a transmitter or as a signal processing part in a switching part, each signal part including a time control part including: a first gate circuit having “wait”and “run”signal outputs, a first shift register, connected to an input of said first gate, for disabling the “run”signal upon the occurrence of a predetermined preamble of a control signal on the signal conductor, a second shift register, connected to an input of said first gate circuit, for activating the “wait”signal upon cessation of an address portion of said signal, a third shift register, a second gate circuit, responsive to a disabling of said “run”signal, for generating an output signal for ensuring that said address portion is entered into said third shift register, a comparator for comparing the address in said third shift register with a fixed address and generating an output signal indicative thereof, a relay adapted to be activated by said comparator output signal indicating a positive comparison, a fourth shift register for storing a control signal having a preamble and said fixed address, coupled so as to be controlled by an output of said second gate circuit, and a switch for activating said second gate circuit for causing said fourth shift register to provide its contents to said signal conductor.
