Question: I need a pressure switch for air. Will this work?
Document: Arrived quickly and was exactly as advertised.My old switch just rotted away from age, corrosion on the contacts. This is a cheap and easy replacement and at this price, I think I'll even order another one to have on hand. The directions were good enough and the switch is solidly built. Personally, I used a sharpie and drew the color code diagram off the original switch right on the air tank so I won't have to fumble around so much next time.
Pressure switch was exactly what I ordered. Came in the mail quicker than I anticipated. Was easier to search on internet than to try dozens of phone calls searching locally.
This is a decent pressure switch. Is working as advertised. However, it is markedly cheaper, lighter, and not as well built as past models. I see that they moved their manufacturing again.I would be happy to pay a few dollars more to get the old quality back but that isn't likely to happen.Only time will tell if the cheaper materials have an adverse affect on lifespan.
The switch that came with the equipment was broken, and most of the data were unreadable, and I couldn't find a replacement but here. It fitted and now it's working perfectly.
Switch is exactly what I wanted and performs perfectly and was very easy to install with normal hand tools and teflon tape.
Excellent pump switch with added protection for pump if for some reason pressure should drop off. Replacement was an easy task.
Direct replacement switch for a reasonable price. I usually have good luck with square D.  Works great while protecting pump from burnout if pump looses all water.
If you have a well, keeping a spare pressure switch is insurance against having NO water without a trip in to town or expensive call to repair person.
Item received quicker than expected, and was the exact item purchased. Installed it, and it works as expected (although there was no info regarding the "Low Pressure Cutoff" feature, but I figured it out).
Worked as expected and easy to install. The install was simply turning off the power (important), opening a faucet in the basement to remove the water pressure, removing the 2 sets of wires, unscrewing the old switch and then reversing the process for the new switch. 15 minutes tops. Now when my water pressure drops below 20 lbs the switch cuts off preventing the pump to run in a dry well. Sometimes if we have a lot of water use the outflow is faster than the well can recover.
Answer: yes
