Abstract (en)
[origin: EP0778597A2] The switch has a movable contact part (18). This cooperates at least with a first counter contact (19) forming, with this, a first switch contact (20). This contact is opened or closed in dependence in the temperature of the switch mechanism (16). The switch has at least a first heat resistor (35). This resistor is provided on the movable contact part (18). The switch may also have a second heat resistor which may also be formed on the movable contact part (18). This cooperates with a second counter contact forming a second switch contact. The second switch contact has a switch state opposite that of the first contact. The switch mechanism may be formed as an alternating switch. In a first switch state, in which the first switch contact is closed, the first heat resistor is connected in series between switch terminals. In a second switch state, in which the second switch contact is closed, the second resistor is connected in series between a different pair of terminals.
