Ingersoll Rand OEM 23474661 Pressure Switch for SS3 And SS5 Single Stage Compressors

Ingersoll Rand OEM 23474661 Pressure Switch for SS3 And SS5 Single Stage Compressors

The Ingersoll Rand 23474661 pressure switch is used on the SS5L5 and SS3L3 reciprocating air compressors. This switch is preset to 95-135psi and includes a pre-installed on/off lever and head unloader valve. The pressure switch turns the compressor on when it hits the lower pressure setpoint and kicks the compressor off when the upper setpoint is reached.

The unloader valve is swivel based and can be adjusted to fit the unloader tube if needed. The pre-set cut-in pressure is 95psi and the cut-off pressure is 125psi providing a 30 psi pressure differential. The 23474661 utilizes a single threaded port on the bottom and includes an on/off switch.

Typically the pressure switch needs 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 the blow off). This results from the contacts being welded together over time. If you find your pressure switch is constantly leaking out of the unloader line, you should consider changing the check valve instead. Please call or email our parts department if you need help sourcing a check valve.

This is an OEM switch from Ingersoll Rand. 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.
