Abstract:
A switch, comprising:a temperature-dependent switching mechanism comprising an electrically conductive spring disk which carries a movable contact element and operates against a bimetallic snap disk which sits approximately centeredly on the movable contact element;a housing for containing said temperature-dependent switching mechanism and including a lower part and an upper part closing off said lower part;said lower part having a first countercontact on its inner bottom and said upper part having a second countercontact on its inner side;the spring disk being braced at its rim against one of the countercontacts and pressing the movable contact element against the other countercontact when the switching mechanism is below its response temperature;wherein the countercontact against which the spring disk is braced at its rim below the response temperature is magnetic; andwherein the first countercontact is configured as an electrically conductive ring.
