Thermal Switches Bimetal

Product Item: Thermal Switches Bimetal
Category: Bimetal Switch
The KSD301 series is a temperature switch that uses a bimetal as a temperature sensing element. When the appliance is working normally, the bimetal is in a free state and the contacts are in a closed state. When the temperature reaches the operating temperature, the bimetal is heated to generate internal stress and quickly act to open the contacts and cut off the circuit, thereby controlling the temperature. When the appliance cools down to the set temperature, the contacts close automatically and resume normal operation. Widely used in household water dispensers and electric boiling water bottles, disinfection cabinets, microwave ovens, electric coffee pots, electric pots, air conditioners, glue dispensers and other electric heating appliances.
