The bimetallic thermostat is a device, with cyclic operation, that allows the temperature to be controlled between two values by automatically activating or deactivating a connected electrical circuit.
A thermostat with normally closed contacts will disconnect the circuit when the set temperature is reached, while one with normally open contacts, on the contrary, will close the contacts once the temperature is reached.
Likewise, once the temperature of the bimetallic disc has returned to the specified reset temperature, the contacts will automatically return to their original state.
