DEFINITION

Classification: 335/106

(under subclass 2) Subject matter wherein the switch structure includes a plurality of fixed contacts each one of which, either singly or in a common group, is adapted to be connected to a separate independent external electrical circuit in such a manner that upon being contacted by a movable contact, or contacts, operated by the magnetic control means, a separate distinct electrical circuit is completed therethrough.

(1) Note. For purposes of classification in this or the indented subclasses auxiliary contacts, whose purpose is to control some function of the switch itself, in addition to main circuit controlling contacts, are not considered as comprising plural contacts.
