ABSTRACT:
A thermal switch includes a low abrasive and wear resistant disc seat for holding a bimetallic disc. The disc seat includes a disc body with a flange extending from a periphery of the disc body. A centralized through opening may be located in the disc body to prevent warping of the disc body during its manufacture. In addition, the disc seat may be made from brass where at least a first surface of the disc body is plated with Teflon Electroless Nickel, which may take the form of sub-micron particles of polytetrafluoroethylene with auto-catalytically applied nickel.
