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 to the normal working state Please note: It is recommended to disconnect electrical appliances from all public facilities before installing thermal fuses. If you are unsure how to choose or replace, it is best to consult professional maintenance personnel Before purchasing: please pay attention to the shape of the contact terminal and ensure that it matches the original shape. This is very important for ensuring compatibility. Determine whether your original machine requires a normally open (NO) or normally closed (NC) switch
