Patent ID: 7109840

Claim:
A motor protector comprising an electrically conductive header having a longitudinal axis and a generally planar top surface, the header having first and second terminal pins mounted in respective apertures along the longitudinal axis and being electrically separated from the header, the pins each having a free end spaced above the top surface of the header, first and second stationary electrical contacts supported on and electrically connected to the respective first and second terminal pins and lying in a plane generally parallel to the planar top surface of the header, an electrically conductive, snap acting thermostatic disc having a top and a bottom surface and a central portion, first and second movable electrical contacts mounted on the bottom surface of the thermostatic disc, an electrically conductive heater and support member having an end portion and a disc support portion, the end portion of the heater and support member welded to the header with the disc support portion spaced above the top surface of the header, the central portion of the snap acting thermostatic disc being mechanically and electrically connected to the disc support portion of the heater and support member and being in close thermal coupling therewith, the movable electrical contacts being disposed generally in alignment with and movable into and out of engagement with the respective stationary contacts in dependence upon the temperature of the thermostatic disc, and a dish shaped cover received over the header and being welded there to form a hermetic switch enclosure.
