The aluminum cover of this thermostat is in contact with the heating element. The bimetallic strip inside the thermostat is a circular metal strip with an arc. After heat conduction and absorption, due to the different expansion rates of the materials on the two surfaces, the bimetallic strip deforms and pushes the lower mechanical structure to separate the silver contacts, breaking the circuit and cutting off the power to the heating element to cool down.
