Compressor switchTuesday, October 30, 2012
The pressure switch was a direct replacement for the sears air compressor I purchased 30 years ago
Installation time was minimal
Flame colored paint for the sides?
Pressure Switch ReviewWednesday, October 03, 2012
This is 95-125psi, 30psi pressure differential switch with a separate electrical cut-out switch. Though it says in the information leaflet that, This switch does not have a adjustable pressure differential” at the same time it also says “Check switch operation after resetting” and another statement under Range Adjustment: Turn the range nut (A) clockwise for higher cut-in and cut-out. Turn it counterclockwise for lower cut-in and cut-out. It was cutting at 140-145 psi and not at 125 psi as it should. I adjusted the range nut (A) i.e. turned it counterclockwise but in reality it is not adjustable and it is still trying to cut-out the compressor at 140-142 psi. The compressor still stays on unnecessarily for a very long time.
The separate electrical cut-out switch
Work as per specs

SPOT on! Exactly what I needed at a sweet price.
I'd Do It Again, And SoonThursday, March 08, 2012
I was about to give up on buying over the internet, then my wife said she found it, and the cost was way better than the others offered. What was the best was the pics that are shown so you could see the exact product at different angles.
Without this, compressor would not work
It is all it can be
Pumptrol Compressor SwitchTuesday, February 14, 2012
Had an old oil-less pancake compressor that was constantly bleeding air causing the motor to stay on. Spoke to Drill Spot sales and Square D techs and they recommended replacement of Pumptrol. After playing around for 45 min, it's still bleeding air but motor waits till pressure drops to lower level before kicking in.
Drill spot has no real tech support. I had to call square D. After a long-winded conversation, they said the problem is probably with the check valve. Isn't the check valve on their product?
Square D for LessFriday, November 18, 2011
Price was way lower than anyone else. Shipping was only two days. DrillSpot is the real deal!
Easy install, good instructions and made in North America.
Wire clamps are not included.
Perfect ReplacementSaturday, September 17, 2011
It was the perfect replacement for what Sears had told me was no longer available.
Application and price.
There were no instructions with the product to assure me of correctly attaching the wiring and/or air tube.
Great Product, Great PriceTuesday, August 16, 2011
It was a great price especially considering we had already bought 2 locally and paid twice the price and they didn't work like they were supposed to!!
Fast shipping and great price!
Found What I Needed at DrillspotMonday, May 02, 2011
I needed a replacement Pressure Switch for my compressor. I looked at all the stores in my area and none of the stores carried the part I needed. I Found Drillspot online and their catalog made it easy to find the part that I needed. I received the part fast and now my compressor is back in service. Drillspot is now listed in my favorite online locations and I am sure I will be going to them again soon.
It was what I needed.
Easy to InstallMonday, April 25, 2011
Easy to install, worked well with my home depot 60 gallon air compressor. Had to buy some small fittings to make it work.
Good ProductThursday, December 30, 2010
Works good. Just what i was expecting!
The install instructions could have been more clear
Square D Air Compressor Pressure SwitchThursday, September 23, 2010
This is a perfect replacement switch for our old Ingersoll-Rand air compressor. This compressor is in continuous daily use so the pressure switch is getting a good workout. I installed it about three months ago and the contacts still look like new and the cut in/out pressures have not drifted. We also use a Square D pressure switch on our well pump and it works flawlessly so I expect many years of trouble free service from this switch as well.
Excellent quality of construction. Established Brand. Good price. Fast delivery. Great service from Drillspot. Will shop again and recommend.
Performs as expected. No problems noted.
Wow!Tuesday, February 10, 2009
I received this product within 3 days of ordering it. I installed it on my compressor and it works as advertised. I would recommend others to buy this product from Drillspot.com.
Good price, fast delivery, good product
None so far
