    • 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.
    • 公开了一种双温度恒温器,其中两个双金属卡盘连接以分开操作两个开关机构。 卡盘被保持在形成在保持杯中的单独的,大致同心的盘形座中。 主体设置有第一邻接表面以将内盘保持在其座中,以及多个对称定位的突起,其延伸穿过内盘中的开口并提供接合外盘并将其保持在其座中的抵靠处。 基座和座椅成比例,使得两个盘在操作期间不能彼此接触。
