Abstract

The switch has an insulating carrier (16) incorporating 2 external terminals (11,14) between which a current path is provided via a temperature-responsive switching mechanism (19) having a switch element (22) which alters in geometric shape in dependence on the temperature, for movement between the closed and open switch positions. The switch element is mechanically and electrically connected in series with a setting element (21), with a flat electrode (12) attached to one of the external terminals supporting one end of the setting element, provided on its inside with a self-holding resistance, connected electrically between the electrode and the second external terminal.
