Termostat Mehanicheskij Shema -

. It operates by translating temperature changes into physical movement to open or close an electrical circuit or a valve. ⚙️ Operating Principle

The wire sending power to the heater, fan, or valve. termostat mehanicheskij shema

When the room cools down, the bimetal strip or bellows relaxes and snaps the contacts closed. Electricity flows to the load. Once the desired temperature is reached, the mechanism expands and forces the contacts open, cutting off the heat. ⚖️ Advantages and Disadvantages Advantages Disadvantages

Mechanical thermostats rely on the laws of physics and thermal expansion. There are two main types of mechanisms used in their design:
