Heater Thermostat

This type thermostat is temperature sensitive switch that controls automatically the operation of heating devices by responding to changes in temperature by sensing the ambient temperature, and changes of ambient temperature are sensed by a temperature sensor (a bimetal disk). The temperature sensor is displaced in its curvature state when its temperature exceeds a first set temperature, and later returns to the initial curvature state when the temperature of the heat sensing element drops below a second set temperature.
