Abstract
A digitally coded electrical supply system is provided for the selective control, through a plurality of code transmission conductors, of electrical power through a single power bus to a large plurality of electrical loads. The system includes a number generator for sequentially and cyclically producing digitally coded numbers into a plurality of code transmission conductors, a plurality of load decoders, a plurality of power switches, a power bus and a plurality of electrical loads. The system also includes a plurality of switch decoders, and a plurality of electrical switches, each switch connecting one of the switch decoders to one of the load decoders through a common activator conductor. In operation, the closing of any of the electrical switches is effective, in cooperation with the connected one of the switch decoders and the common activator cable, to activate an associated one of the load decoders and to supply electrical power to the associated one of the electrical loads.
