Thermostat (also called thermostat switch, temperature protector, temperature controller in English) refers to a series of automatic control elements that physically deform inside the switch according to the temperature change of the working environment, thus producing some special effects, or the temperature is transmitted to the temperature controller through the temperature protector, and the temperature controller sends the switch instruction, thus controlling the operation of the equipment and achieving the ideal temperature energy-saving effect. It is widely used in various household appliances, such as drinking fountains and energy saving. Thermostats can be divided into jump thermostats, liquid expansion thermostats, pressure thermostats, electronic thermostats and digital thermostats.
