Abstract
A structurally simple thermostat is disclosed in which a single rivet provides the mounting of all of the switch elements. The switch elements are located by the rivet and by a portion of the contacts substantially spaced from the rivet to minimize the affect of manufacturing tolerances in the positioning of the switch elements. A single terminal element supports the movable contact, provides a terminal extension and closes the switch cavity. The structure is arranged so that ceramic material can be used for the non-metallic parts with a minimum effect created by the relatively loose dimensional tolerances required in the manufacture of ceramic parts. The terminal member is formed with a shallow dish shaped projection which prestresses the rivet assembly to prevent looseness resulting from differential expansion.
