ABSTRACT:
A temperature-dependent switch has first and second external terminals arranged at an electrically conductive lower housing part and an insulating cover part, respectively. Within said lower housing part there is arranged a temperature-dependent switching mechanism having a bimetallic snap disk and an electrically conductive spring disk carrying a movable contact element that is configured integrally with and as a dome on the spring element. Depending on the temperature of said bimetallic snap disk said spring element is in electrical contact with said first terminal and via said movable contact element with said second terminal.
