DEFINITION

Classification: 337/363

(under subclass 362) Subject matter including significant details of at least two or more contact pairs operative in such a manner that at least two or more separate and distinct electrical circuits may be controlled by the bimetallic contact actuating means. One of the plurality of contacts may be common to more than a single contact pair.

SEE OR SEARCH THIS CLASS, SUBCLASS:

41+, for electrothermally actuated switches having bimetallic elements combined with mechanical contact operating means.

86+, for electrothermally actuated switches having a plurality of contacts directly driven by the bimetallic element or elements.
