Bimetallic thermostat KSD series

KSD series disc thermostat is mainly applied in occasions where the circuit should be automatically switched on or off as the temperature changes, keeping the temperature of the electric devices varying within a certain range. According to customers’ requirements, we can choose different insulation materials for the bimetal thermostat, like phenolic resin, PPS, and ceramic. With fixed working temperature, reliable operation, and long service life, disc thermostat has found large popularity in electric appliances like boiler, water heater, vacuum cleaner, duplicator, electric stove, oven, dryer, refrigerator, dishwasher, and air conditioner, etc. Working Principle The mechanism of KSD series snap action thermostat is based on a snap-action bimetal disc, which opens or closes the electric contacts when the predetermined temperature is met. When the electric device works normally, the switch is closed. Once the temperature reaches the limit point, the bimetal disc works immediately to open the contacts and thus switching off the circuit. After the device has cooled down to the allowable temperature, the snap disc thermostat will reset automatically.
