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.
