How the thermostat works

Thermostat is made according to the principle of object heat rise cold shrink and become.

Heat expansion and cold contraction are the common characteristics of objects, but different objects have different degrees of heat expansion and cold contraction.

The two sides of the double piece of gold are conductors of different substances. Under the changing temperature, the double piece of gold will bend due to the different degree of expansion and contraction, and the set contact or switch will be touched, so that the set circuit (protection) will start working.

This is the basic working principle of the temperature controller and production ideas.
