Direct replacement part

The Ingersoll/Rand 46818555 pressure switch is a new pneumatic component built for reciprocating compressor systems. It fits SS3 and SS5 series units and matches Grainger part numbers 4YW09 and 4YW10. The kit includes the main switch (23474661) and three tube assemblies (23524796, 23524804, 46818548) plus unloader parts for CV and SS models. Buyers needing a different pressure range or thread type should verify specifications before ordering.

Solid-state reliability

This switch contains no moving mechanical contacts, so it avoids the wear and arcing that degrade traditional electromechanical units over time. Operation stays consistent across the compressor duty cycle without audible clicking or contact bounce. Power draw is limited to the coil circuit, adding negligible load to the control voltage supply. Installers who need adjustable cut-in or cut-out pressures will find this model fixed at the factory setting.

Upgrade from worn electromechanical switches

The kit replaces ageing pressure switches that have drifted out of calibration or suffer from contact pitting. It restores reliable start-stop control without rewiring the motor starter. The jump is worth it when the original switch causes short-cycling, fails to unload, or trips the overload repeatedly. Shops standardising on Ingersoll Rand SS3 or SS5 fleets can stock this single part number for multiple machine variants.

Questions about this item

How is the Ingersoll Rand 46818555 pressure switch installed and which step is commonly missed?

Mount the switch, connect the four tube assemblies (23524796, 23524804, 46818548, and the unloader line), then wire the 23474661 switch contacts; the step often missed is tightening all four tube fittings to prevent air leaks.

What maintenance or replacement will the 46818555 pressure switch need over time?

Inspect the three tube assemblies and unloader valve for cracks or carbon buildup annually; replace the 23474661 switch element if cut-in or cut-out pressure drifts beyond the compressor's specified range.

What limit appears first on the 46818555 pressure switch during sustained compressor cycling?

The 23474661 switch contacts wear from repeated actuation, causing pressure-setting drift before the tube assemblies or unloader valve show fatigue.
