DEFINITION

Classification: 337/135

(under subclass 131) Subject matter including significant details of a flexible vane or plate means whereby the snapping action of the contacts is caused to take place. The vane or plate may control the action of a movable contact, or contacts, by its inherent tendency to change curvature when heated or it may be under the influence of a further temperature responsive element such as a wire or ribbon which exerts a deforming force on the vane or plate upon the passage of a heating current therethrough.
