THERMAL SWITCH AND METHOD OF ASSEMBLY AND TOOL USED THEREIN 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. An end of the striker pin has a cap fastened thereto 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 placing a mass of adhesive within the cup-shaped cap and pressing the end of the striker pin into the cap to provide flow of adhesive along the striker pin until said pressing is discontinued to provide a controlled thickness layer of adhesive remaining within the cap and between the cap and the end of the striker pin, which is then set with the parts held in a predetermined relation. A tool used in the method comprises a magnetic fixture having a central opening with a bottom wall to receive the cap and hold the cap in position as the striker pin and cap are brought into said predetermined relation.
