Thermostat is a device in ovens which helps to maintain a temperature by:
breaking the circuit
breaking the circuit is correct.
A thermostat in an oven uses a bimetallic strip made of two metals that expand by different amounts when heated.
When the oven reaches the set temperature, the strip bends and breaks the circuit, switching off the heating element. As the oven cools, the strip straightens and reconnects the circuit, so the temperature stays near the set value.
