The principle of generating instant beating. through the role of institutions. Make the contacts move quickly to achieve the purpose of disconnecting or connecting the circuit. its working temperature
Fixed, no need to adjust: the action is reliable and crisp. Small arc; long service life; less radio interference.
According to the temperature change of the working environment, physical deformation occurs inside the switch, thus producing some special effects, producing a series of automatic control elements for conducting or disconnecting action, called temperature switches, also called temperature protectors or temperature controllers, referred to as thermostats. Or use the over-protector to transmit the temperature to the temperature controller, the temperature controller issued a switch command, so as to control the operation of the equipment to achieve the desired temperature and energy-saving effect.
As the use of butterfly-shaped bimetal as a temperature sensor components, the temperature controller works as follows: when the temperature rises, the butterfly will produce a corresponding deformation, and when the temperature reaches the value of the butterfly deformation, the butterfly sudden jump relying on the mechanical drive of other devices, so that the contacts quickly act to turn on or cut off the current.
Normally closed.
Temperature switch original state contacts are closed, when the sensed temperature exceeds the rated temperature contacts open.
Normally open.
Temperature switch original state contact is open, when the sensing temperature exceeds the rated temperature contact is closed.
