DEFINITION

Classification: 337/37

(under subclass 36) Subject matter comprising manual or other mechanical means acting conjointly or cooperatively with at least one bimetallic device, or which acts as an intermediary between an electrothermal responsive bimetallic element and at least one movable contact thereby opening or closing an electrical circuit. The manual means may be a handle or push button actuated means, for instance, or the other mechanical means may be a motor, for example.
