ABSTRACT:
A dual temperature thermostat is disclosed in which two bimetal snap discs are connected to separately operate two switch mechanisms. The snap discs are retained in separate, generally concentric disc seats formed in a retainer cup. The body is provided with first abutment surfaces to maintain the inner disc in its seat and a plurality of symmetrically positioned projections which extend through openings in the inner disc and provide abutments which engage the outer disc and maintain it in its seat. The abutments and the seats are proportioned so that the two discs cannot contact each other during their operation.
