(under subclass 313) Systems which include at least two load device circuits and an electric switch having two or more contacts each of which is connected to a different one of the load device circuits, the cooperating contact means being arranged to close the circuit from the source of supply to one of the load devices to the exclusion of the other.
SEE OR SEARCH THIS CLASS, SUBCLASS:
64, for multiple filament load devices which have an electric switch structurally combined therewith, the switch being designed to close the circuit to one of the filaments to the exclusion of another.
83, for this subject matter where the load devices are claimed as being vehicle (automobile) headlight systems.
211, and indented subclasses, for this subject matter where the system includes a periodic distributor type switch which periodically connects different ones of the load devices to the source of current supply in timed sequence.
317, for systems under subclass 313 wherein the system includes a switch for closing the circuit to three or more load device circuits in progressive order.
320, and indented subclass, for systems under subclass 313 wherein two or more switches are provided so that any one of two or more load devices may be supplied with current. SEE OR SEARCH CLASS
