Description:

H20 thermal cutoff switch is a temperature control switch developed by imported thermal bimetal. It uses high sensitive disk-shaped bimetal strip as the temperature-sensing element. H20 thermal cutoff switch composed of bimetal strip, moveable contact, stationary contact piece, fixed base, moveable spring piece, case and temperature resistance lead wire. When the electric equipment work normally, the bimetallic strip in free state, the contact is in closing/opening state, when the temperature reached operating temperature, bimetallic strip is heated to produce internal stress and fast action, open/close contact, cut/processing circuit, and temperature control.When the appliance is cooled to the reset temperature, the contact will automatically close/open and return to normal working state. H20 thermal cutoff switch has the features of small size, rapid action, accurate temperature control and long life cycle. It is widely used in all kinds of electric motors, coils , household applliance and power tools.
