Ingersoll Rand OEM Pressure Switch for SS5N5 Air Compressor 54627104
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.
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.
Note this pressure switch is only for the SS5N5 which is on an 80 gallon receiver. The majority of Ingersoll Rand SS5's sold were SS5L5 which are on a 60 gallon receiver and uses pressure switch part number 23474661. Please contact us if you would like confirmation this switch will work with your compressor.
