Structure and application:

The temperature controllers take bimetallic strip as the temperature-sensing unit. In case of normal operation the electrical appliance, the bimetallic strip is in a free state; the contact point is in a state of close/open. When the temperature reaches the action temperature, the bimetallic strip performs quick action, When the electrical appliance is cooled down to the recovery temperature, the contact point can not automatically reset , the people should press down the reset handle with acting force if the contact need to be reset once again, in this way ,the thermostat control the disconnection and connection of circuit. (Note: 1) It is necessary that you should only press down the reset handle when the temperature drop down by 20°C after the contact action. 2) In order to make sure the normal operation of thermostat, the vertical space between reset handle and thermostat temperature sensing cover should be more than 20.4mm.)

Widely used in electrical heating appliances like water dispenser, water heater, sandwich bread baker, dishwasher, dryer, sterilizing cupboard, micro-wave oven, electric heating coffee pot, electric cooker, refrigeratory, air-conditioner, laminator, heater of auto seat.
