bimetal thermostat diagram

KSD9700 series product is a kind of thermostat which adopt the bimetal disc as the temperature sensing element. The bimetal disc is in free state and the contacts are closed /open when the electrical appliance is working in normal condition, when the ambient temperature raises to the preset operating temperature, the contacts open/close as the bimetal disc deforms to jump when being heated, then the circuit is cut off/on to control the temperature. Then the contacts will close automatically to cut on the circuit when the electrical appliance is cooled down to the reset temperature, This product is widly used in home appliance’s motor and electrical equipment, such as air conditioner motor, transformer, thermal appliances, etc.
