Abstract

The switch has a switch mechanism (12) which switches on excessive temperature, to open and close a switch circuit which connects the terminals (26,38) of the switch (10). The switch mechanism (12) has an electrically conductive spring part (29). This acts against a bimetallic component (33) in dependence on the temperature of the latter. In its relaxed state, the spring part (29) is electrically connected to an external terminal (38). It also carries a movable contact (28) which is connected to a fixed contact (24) in dependence on the temperature of the bimetallic component (33). The fixed contact is electrically connected to the other terminal (26). The movable contact (28) is formed integrally with the spring part (29). The movable contact is preferably formed as a curved surface or bump on the spring part. The bimetallic part may be a bimetallic snap plate arranged over the bump (30).
