Abstract of the Disclosure A thermal switch having contacts with one contact being movably mounted on a carrier and with movement of the carrier controlled by a bimetal actuator disc. The actuating movement is transmitted through a striker pin of molded ceramic material which is fastened in fixed relation to the carrier by a layer of adhesive of controllable thickness to establish the effective length of the striker pin. The method of manufacturing the thermal switch embodies holding of the striker pin in fixed predetermined relation to components of the thermal switch. During movement of the parts to this position, a mass of adhesive carried at an end of the striker pin is pressed between the end of the striker pin and the carrier to provide lateral flow thereof until said pressing is discontinued to provide a controlled thickness layer of adhesive which is then set with the parts held in a predetermined relation. A tool used in the method comprises a disc having a central opening with a bottom wall to receive a lower part of the striker pin and hold the upper end of the striker pin oriented for movement relative to the carrier as the components are brought into said predetermined relation.
