DEFINITION

Classification: 337/76

(under subclass 70) Subject matter wherein the bimetallic element is specifically described as performing another function other than the primary or latching function. For example, the element may constitute a contact bridging means or even one of the main switch contacts.

(1) Note. The line between the apparatus found in this subclass and that to be found in the subclasses 85+ and 362+ is: in this subclass the latch and/or trip comprises a part of a mechanical operating means interposed between the bimetallic actuating means and the main contacts while in the subclasses 85+ and 362+ the bimetallic element actuates at least one movable contact directly without the intervention of any mechanical means.
