Product Details
Product introduction:

KI 31/KSD301 series snap action temperature controller, also known as 1/2 inch bimetal snap disc thermostat, belongs to the mechanical action temperature controller switch. To achieve the dynamic/static contact on the internal structure of the temperature controller disconnect, so as to open the temperature control or temperature protection function by highly sensitive bimetallic sheet through thermal deformation principle. 

KI 31/KSD301 ceramic temperature switch, using ceramic (chemical name: 95 ceramic),its high temperature resistance, high strength, high density, strong insulation performance, not easy to deformation, environmental protection, temperature controller is often used in high temperature environment carrier material, often used in 300℃ working environment temperature controller.
