Abstract

The electrical switch has a body (12) into which are set a pair of electrodes (22,23). In normal operation the electrodes are connected via a movable contact element (17) that is mounted on a spring disc (18). Positioned between the spring disc and the housing is a bimetallic element (19) that responds at a set temperature to cause the connection to break.
