Description:
KSD301 thermal switch’s Principle and structure
The main principle of KSD301 series thermostat is that one function of bimetal discs is snap action under the change of sensing temperature. The snap action of disc can push the action of the contacts through the inside structure, and then caused on of off the circuit finally. The main characteristic are the fixation of working temperature, the reliable snap action, less flashover longer working life and less radio interference.
KSD301 thermal switch’s application
1.Household electric appliances: water dispenser,electric water pots,toaster,dishwasher,drying machine, disinfection cabinet, microwave oven, electric kettle, electric caldron, refrigerator,air-condition,laminator etc.
2. Office equipment
3. Car seat heat, car deicer
