موديلات تفاصيل "Pressure Switch for Air Conditioner or Heat Pump or Refrigeration system"

Miniature pressure switch An electric switch that closes or disconnects the control circuit as the pressure of the controlled medium rises and falls. It is widely used in refrigeration units, various air conditioners, oil pumps and air pumps, and other industrial equipment that needs to adjust the pressure of the medium by itself to protect the pressure system.

Working principle: When the pressure of the controlled medium rises to a certain set value, the butterfly-shaped metal diaphragm will be unstable and jump. By pushing the ejector rod, the switch contact is connected (or disconnected). When the pressure of the controlled medium drops to another set value, the butterfly-shaped metal diaphragm will suddenly jump back to its original state, causing the switch contact to be opened (or connected), thus realizing the function of the switch.

When the pressure of the controlled medium decreases, the switch cannot automatically reset, and the circuit always maintains the state after the conversion. Only when the reset button is pressed by hand, the circuit returns to the original state.
