How about a bimetal thermostat?
Regarding the bimetal thermostat, it is a device that uses some of the characteristics of metal to control the temperature. At this time, the metal is controlled by the switch.
1.Under normal temperature, the contacts of the copper sheet and the spring sheet are connected, so they are energized. When the temperature rises, the active layer expands more than the passive layer, so the bimetal will move towards When the temperature rises to a certain degree, the circuit will be disconnected. When the temperature drops, it returns to its original state, the bimetallic strip recovers, and the circuit is turned on at this time.
2. When the temperature of the product rises and conducts heat to the bimetal thermostat through conduction, the temperature of the bimetal thermostat changes, and when the temperature reaches a certain level, it will jump. Make the electric shock open or close.
3. When the temperature of the product drops and resets to the original temperature, the temperature of the bimetal thermostat will also change accordingly, and the bimetal will return to its original shape in form, jump, and realize electric shock disconnection or closure.
4. Based on the above, the concept and working principle of the bimetallic thermostat are introduced respectively. The working temperature of the bimetal thermostat is stable, crisp and clean, and has a longer service life. It is not subject to radio interference. The structure is more precise and the functions are more complete. It is a better performance in the thermostat.
