Working principle :
CTR Series Magnetic temperature switch is a combination of temperature-sensitive ferrite materials, permanent magnetic materials and the reed pipe. It is made by using the principle that temperature-sensitive ferrite material will lose permeability near the Curie temperature, make a tremendous change through magnetic flux in reed pipe so as to make the reed pipe contacts open or close, which is to automatically disconnect or connect the circuit.
