Ingersoll Rand Two Stage Reciprocating Compressor Pressure Switch Replacement – 23474588

23474588 is an OEM pressure switch manufactured by Ingersoll Rand. This is a common pressure switch used on IR’s two stage Ingersoll Rand reciprocating air compressors. The pre-set cut-in pressure is 145 psi and the cut-off pressure is 175psi providing a 30 psi pressure differential. This was most commonly used on their two stage full package models with head unloaders.

Note that this pressure switch does not include an on/off switch. This switch is only used on IR compressors that included a magnetic motor starter. There is a switch on the motor starter that is used to turn the compressor on and off.

This IR pressure switch utilizes 4 threaded ports on the bottom to attach the safety valve and pressure gauge. No unloader valve is included with this switch as the compressor it’s meant to be paired with utilizes a pilot valve and centrifugal unloader.

The pressure switch will often need to be replaced if the compressor does not turn on at the lower setpoint or does not turn off at the upper pressure setpoint causing the safety valve on the tank to pop. This results from the contacts being welded together over time.

Plenty of aftermarket switches are sold online, but many of them are not rated for the full load amp draw of the compressor and will cause pre-mature wear to the switch. The OEM switch from Ingersoll Rand is rated for a higher amp draw and is much heavier duty compared to others.

This is a newer version of the original switch. The older part numbers for this were 56288780 and 56288798. Please contact our parts department for confirmation this will work with your reciprocating air compressor.
