Title: Temperature responsive electrical switch construction and method of making the same

Abstract: A temperature responsive electrical switch construction having a housing provided with a chamber therein. A pair of spaced apart contacts project into the chamber and are adapted to be bridged by a bridging member disposed in the chamber and being operatively interconnected to a bimetal member also disposed in the chamber whereby movement of the bridging member relative to the contacts is in relation to the sensed temperature of the bimetal member. The housing has a threaded adjusting arrangement for initially adjusting the contact pressure between the contacts and the bridging member when the bimetal member is sensing a certain temperature without effecting the operating temperature of the electrical switch construction.
