DEFINITION

Classification: 315/317

(under subclass 313) Systems having three or more load device

circuits.

SEE OR SEARCH THIS CLASS, SUBCLASS:

68, for multiple filament lamps having three or more filaments and having an electric switch structurally combined therewith so as to form a unitary device.

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

211, 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.

314, for this subject matter where the switch means is a preselectable switching system. 316, for this subject matter where the switch means is operated by keyboard means or is controlled by a pattern.
