LF10-4H Pressure Switch, 4 Port Air Compressor Pressure Switch Replacement Control NPT1/4 95-125 PSI 20A

This fit OK and works well with good adjustments. I fitted this to a 1958 compressor, with a 2HP motor and it has been doing well for me.

I ordered this part for my dad to replace the switch on his air compressor. It’s the portable kind. It seems to be working well and he had no trouble putting it on. If anything changes I will update this review.

I have a Craftsman Industrial pancake compressor that is at least thirty years old. It is a 120 psi 4 gal. 1.5 horse, 4.6 CFM @ 90 psi. I had a pesky leak and put a new relief valve which turned out to be faulty right out of Lowe’s. In my infinite desire to take things apart, I dismounted the pressure limit switch. As you could guess, I had springs and parts bouncing, grr. 2 days of figuring out how it was originally put together and remount I succeeded on the first part but failed on the second as it kept popping apart. Moral of the story there is Don’t take out the pressure switch off of the manifold!!I The original Craftsman switch was discontinued years ago so I scoured the internet for a replacement.. This unit was the closest I could find to original. It looked like the Same unit but with a different orientation of the manifold,(part where all the air fittings screw in). Because of that, I had to put the pressure relief valve on opposite side and the switch orientation was changed as well. In order the dismount and remount old to new, I had to take the case apart and dismount the compressor motor and set to the side to make room to install. Got it all back together and it works perfect! Great price!Just be aware it is not “plug and play” but if you have any mechanical aptitude you can figure out your application if your original part is discontinued!

Easy installGreat Quality

Five stars! Great price and it works like my previous switch. It has a slightly lower cut in and cut out pressure, however , it is only by 5-10 psig.I installed this on my garage mate ingersoll Rand. Granted I had to rob a brass fitting for my old switch so it would meet up to my copper pipe on compressor , but every switch I looked high and low I would have had to perform the same part swap. No matter what price or model I paid. It works and saved my compressor!!!!Previous switch

This fit our compressor perfectly.
