DEFINITION

Classification: 337/38

(under subclass 37) Subject matter including at least two or more electrothermal current responsive bimetallic elements, combined with a further single mechanical contact controlling means. The bimetallic elements may operate jointly or individually to control the movable contact or contacts

through the agency of the mechanical means.
