What is a Bimetallic thermostat?

A bimetallic thermostat is a device used to detect temperature and control electrical circuits by opening and closing based on temperature changes. This thermostat uses two different metals with different coefficients of expansion. As the temperature rises, the metals expand at different rates, causing the bimetal to bend. This bending action opens or closes the contacts, signaling the system when the temperature has reached the set point. Bimetallic thermostats are widely used in household appliances (such as ovens and refrigerators) as well as industrial equipment. They are known for their simple and reliable design.

Application of Bimetallic thermostat

✅Household Appliances
In ovens or toasters, the bimetallic thermostat operates to stop heating once the internal temperature reaches the set point.
✅Refrigerators
Used in temperature control to activate the compressor when cooling is needed.
✅Industrial Equipment
Used for temperature management in motors and heating devices, automatically cutting power to prevent overheating.
