(under subclass 6) Subject matter wherein the automatic circuit interrupting means consists of two or more separate and distinct devices adapted to jointly or separately interrupt the continuity of a circuit to be controlled. The devices may be connected in series, tandem or any other
desired arrangement provided there is single continuous circuit from a source to a load through the switch means. For example, each switch may be in one leg of a two conductor circuit.
(1) Note. The devices to found here differ from the multiple or polyphase devices in subclasses 8+ above, in that the subject matter relates to devices for interrupting a single polyphase circuit by a single switch means having at least one pair of contacts for each phase.

8+, for multiple or polyphase switches. See (1) Note above.
88+, for plural periodic switches.
152, for plural vacuum or hermetically sealed switches. 159+, for plural electromagnetically actuated switches not specifically recited as automatic circuit interrupter devices and each being operative independently of the other.
