Abstract
A thermal switch includes a thermally responsive plate assembly including a metal support deforming from an initial shape before a header plate assembly is secured to a housing assembly, with a result that a position of a movable contact in the housing assembly is adjusted so as to be within a predetermined height range relative to an open end of a housing. A contact pressure of switching contacts after the assembling is produced by the height adjustment, and subsequently, a neighborhood of a part of the housing to which part the thermally responsive plate assembly is secured is deformed, so that an operating temperature is calibratable.
