Abstract

The switch (10) has a temperature-dependent switch mechanism (12) contained within a housing (11) provided by a base (14) with a counter-contact (16) on its inside surface and a cooperating cover (17). The cover has a second counter-contact (19) on the inside (18). The switch mechanism employs a conductive spring disc (31) carrying a movable contact (32) and a bimetallic snap-action disc (34), fitted around the outside of the movable contact. The spring disc acts against one counter-contact at its edge (33) and presses the movable contact against the other counter-contact below the response temperature of the bimetallic snap-action disc. The counter-contact against which the edge of the spring disc acts is magnetic.
