Adjustable Air Compressor Pressure Switch for hydraulic pumps and Other Applications


Gems Sensors is a leading manufacturer of both adjustable pressure switches and factory set pressure switches. Some typical applications would be as an air compressor pressure switch where the compressor could be set with the adjustable pressure switch to complete the circuit (turn on the compressor) to increase the pressure and then turn off the air compressor pressure switch once the desired maximum pressure set with the adjustable pressure switch has been achieved.72 Similar settings with an adjustable pressure switch can be achieved with a water pump pressure switch where the water pump pressure switch can be set to control the water pressure within a desired pressure range.
