Ingersoll Rand 23474661 Pressure Switch for Reciprocating Compressors

Just put one of these on my SS4L5 model purchased in 2014. The original finally quit on me, the contacts got stuck. I don't use it much probably why it made it 12 years. If this one lasts that long, I'll be all good with it. It fit and works like a champ. Only have one cycle on it butt was super easy to install and a direct fit. The part numbers are the same the listing just doesn't have the SS4 listed as compatible.

Hopefully this pressure switch lasts a little longer. This switch was purchased to replace the switch on our air compressor in the shop. Relatively easy to install and adjust.

The pressure switch failed after several years on my SS5L5 compressor. I was working in the shop and paused to wonder... what is that awful noise. The poor pump head was trying its hardest to shove 145-150psi into the tank, which is apparently the mechanical limit of the pump, and the noise it created was loud, funny if not borderline terrifying. This switch was a drop in replacement and already calibrated correctly. I did have to refabricate the unloader tube in my case as the old and new attach to the switch a little differently but that was simply done with automotive brake line bending pliers.

This was exactly what we ordered. It’s installed and working as expected

Worked great, would be 5 stars but was shipped loose in thin paper bag with no packing, was poking out the side of bag and damaged. A replacement was shipped over night the same way with a smaller hole in bag but undamaged.

OEM quality make sure it is the correct pressure range for your unit?

Was delivered fast, but received in a black bag, no or product info. The air connection was 1/2” instead of 3/8” like most switches are for 5HP Compressors !

Works as it should however my pressure switch came at a 135 to 175 cut off not the hundred to 135 PSI psi. With the pressure adjuster screw all the way out it activates at 105 and shuts off at 140 psi

Direct replacement, just what I needed. Unfortunate that I in fact needed it in the first place, but that’s a different issue. Easy install, no issues. Back up and running. 👍

No funciona bien, es muy común que después de cortar por presión fue el aire no sella la válvula.

My home garage compressor has limited use. After installing it worked initially and after 6 months I noticed that the compressor was not coming on and the pressure dropped way down after checking all the connections were good I decided to give it a tap and the compressor came on and pressured up. When the pressure dropped after use it would not cycle again and after tapping the unit it came back on

This was a rip off! It was seized up, so is useless!

Although the package indicated it was the proper replacement, the actual switch (which looked identical but had a different part number) was for a high pressure system. It's pressure cut off was set for 175 PSI. If installed and turned on, it could cause your tank to explode.
