ABSTRACT:
A heat switch which includes a base body having electrical connection elements fixed thereon and insulated from each other, a movable contact member, a fixed contact member, and a bimetallic member for controlling relative positions of the contact members with respect to each other. Each of the contact members is connected with a respective one of the electrical connection elements in an electrically conductive manner. The bimetallic member is operable for conductively connecting or separating the contact members from each other. The movable contact member is relatively resistant to bending and is connected by an electrically conducting articulated connection with one of the electrical connection elements. The articulated connection includes an articulation part formed on one of the connection elements and a movable articulation part formed on the movable contact member. The articulation parts are rotationally slidably and electrically conductively applied against each other and resiliently pressed toward each other by a spring force.
