KSD301(5A, 10A,16A 125v / 250v) series product is a kind of temperature control switch that uses bimetal as the temperature sensing component. When the electrical appliance is working normally, the bimetal is in a free state, and the contact is in a closed/disconnected current state. When the temperature reaches the operating temperature, the bimetallic strip is heated to generate internal stress and act quickly, opening/closing the contacts, cutting/connecting the circuit, and thus plays a role in temperature control. When the appliance cools to the reset temperature, the contact opens/closes automatically, and the normal working current state is restored.

widely used in: Water dispenser, water heater, sandwich toaster, dishwasher, dryer, disinfection cabinet, microwave oven, electric coffee maker, electric cooker, refrigerator, air conditioner, glue machine, office equipment, car seat heater and other electric appliances.
