Science popularization of temperature switch principle knowledge

A temperature switch is a temperature control device that uses bimetallic strips as temperature sensing elements. When the temperature rises to the set value, the bimetallic strip is deformed by heat, triggering the switch action to cut off or connect the circuit, thereby achieving temperature protection and control. It is widely used in household appliances, industrial equipment and other fields, such as washing machines, air conditioners, electric heating appliances, transformers, etc. It has the characteristics of small size, insulated shell, sensitive action, and long service life.
