Abstract: A system for distributing electrical energy to the electric current consumer devices of an automobile without having to wire each consumer individually via a switch to the power source, comprising a central control unit connected to a plurality of remote control units by a single control line for each side of the automobile to which respective groups of consumers are connected. A single power line for each side of the vehicle runs from the power source to the remote control units which selectively energize the consumers in dependence on coded pulse signals received from the central control unit. Operation of the system is cyclic and includes time on the control line for a reverse flow of signals from sensors and/or check circuits to transmit to the central control unit for information and/or warning display on an instrument panel of the automobile.
