Working Principle
When the electrical appliance works normally, the bimetallic sheet is in the free state and the contact is in the closed / open state. When the temperature reaches the operating temperature, the contact is opened / closed, and the circuit is cut / closed, so as to control the temperature. When the electric appliance cools to the reset temperature, the contact will automatically close / open and return to the normal working state.
