Air conditioning refrigeration high and low pressure switch
application
This isMainly usedIt is used for high and low pressure protection and control of household, commercial and automotive air conditioning and refrigeration systems, and can also be used for high and low pressure protection and control of air compressors, hydraulic machines, various equipment and tools.
Operation/Working Principle
When the pressure of the medium (liquid or gas) in the pressure system is higher or lower than the rated safety pressure, the disc-shaped metal diaphragm in the system jumps instantly, and the switch contact is pushed through the connecting rod to connect or disconnect. When the pressure drops to the rated recovery value, the disc-shaped metal diaphragm resets instantaneously, and the switch resets automatically.
