DEFINITION

Classification: 315/313

(under subclass 312) Systems having an electrical circuit maker and breaker in the current supply circuit to the load device for selectively controlling the supply of current to the load devices.

SEE OR SEARCH THIS CLASS, SUBCLASS:

64, and indented subclasses, for multiple filament lamps which are structurally combined with an electric switch.

121, for this subject matter where the switch means is an automatic shunt and/or cutout.

154, for this subject matter where there is a switch means connected in the circuit to select the load device to be energized, the switch means being controlled by a radiant energy sensitive device (photocell).

184, for this subject matter where each side of the supply circuit includes a plurality of pairs of conductors, three or more load devices, each being connected to a different pair of the conductors.

186, for this subject matter where there are a plurality of series connected load devices, a periodic switch being included in the supply circuit. 191, for this subject matter where there are a plurality of series connected load devices, the system including switch means so the load devices may be converted from series connected to parallel connected.

193, for this subject matter where there is a plurality of series connected load devices, the system including switching means.

210, for this subject matter where there is a periodic switch which periodically connects different ones of the load devices to the source of current supply in timed sequence.

362, and the subclasses specified in the notes to the definition of that subclass for other systems under the class definition provided with an electric switch in the supply circuit.
