Abstract
A method of increasing the cycle life of a thermostatic disc element for use in a disc assembly used in thermostatic switches in which a weld slug is used to weld the disc element to the disc assembly thereby causing a heat affected zone of the disc element comprising the step of engaging the surface of the disc element opposite the surface adjacent the weld slug with a fulcrum member at a location spaced from the heat affected zone so that upon reversal of the curvature of the disc element, the disc element will bend about the fulcrum member at a location removed from the heat affected zone.
