Abstract

The switch (10) comprises two connection electrodes (12,13) fastened to an isolating carrier (11), as well as a control mechanism which produces a connection between the connection electrodes in dependence on its temperature. A resistance part (18) is connected with the connection electrodes, in parallel to the control mechanism, and is inserted in the interior of the carrier, crosswise to the connection electrodes, so that it is held by it.
