A temperature switch is a switch that determines whether to turn on or off based on the temperature of the object being controlled; According to their different action principles, they can be divided into bimetallic, pressure type, and thermosensitive ferrite type.

1. Thermostat is a series of automatic control components that undergo physical deformation inside the switch according to the temperature changes in the working environment, resulting in certain special effects and conducting or disconnecting actions. It is also known as a temperature control switch, temperature protector, or temperature controller, abbreviated as a temperature controller. Alternatively, the temperature can be transmitted to the temperature controller through a temperature protector, which sends a switch command to control the operation of the equipment to achieve ideal temperature and energy-saving effects. Its application range is very wide, and different types of temperature controllers are used in many products such as household appliances, motors, refrigeration or heating.
