Abstract
A bimetal snap disc thermostat is disclosed which is structured for automated assembly. Such thermostat includes a body with contact supports molded therein in a manner providing sufficient strength so that terminals can be riveted onto the contact supports after assembly. The body and contact support subassembly is structured so that it is symmetrical on opposite sides of a central axis. A disc cup is provided with axial and radial surfaces which accurately locate the disc during and after assembly. Also disclosed is a method of gaging and calibrating the thermostat automatically. Calibration of the spring force of the movable contact is accomplished by sensing the force in a given position and subsequently deforming the spring until a predetermined force exists in such predetermined position. Gaging is accomplished by deforming a projection from the movable contact arm until a predetermined uniform spacing is established between such projection and a gaging surface.
