Bought my truck and it was working great, but the switch went out. I couldn't figure out why it would randomly work. I finally took it apart, unfortunately breaking it in the process. This one fit perfectly and works great.Far less than the "official" part and works just as great.

Bought this to replace the original that some hack installed to power the compressor sans-relay. The original switch had of-course died a horrible electrical death that follows the terrible misapplication of electrons. Its successor (this one) does what it should, triggers the compressor while opening the air-flow path, so it gets 5 stars. No leaks, air bags are happy again. I did not use the included wires as I'd already rewired the old switch properly. Plug and play. The wires were VERY tight and hard to remove but I'm ok with that. Makes them not likely to rattle off when installed. Air connections are barb fittings which was like what it was replacing for me but something to be aware of. I carefully heated the old ones with a heat gun to soften them up for removal/reinstall.

The previous owner decided to bypass installing the relay and running the pump off the switch. Lesson in electronics: ELI the ICE man...Voltage leads Current in and inductive circuit...So every time you open the switch the voltage rises to technically infinite. This is why you get a big spark on a vacuum cleaner when you pull the cord while running. The high voltage will and did ruin the switch. Amazon to the rescue!

This is an exact fit to replace the switch on the gauge panel, a lot cheaper than replacing the whole gauge. Easy to install and Work perfectly.

Worked perfect for my onboard compressor on my 5000 pound Firestone airbag system on the 2019 Chevy Duramax Diesel HD 2500…; mine had the compressor gauge and the switch/activation toggle all in one piece but the switch itself can be changed without buying the actual guage part itself again or the entire switch/toggle and gauge unit; i just got the toggle switch and worked perfect! Would definitely buy again if needed and would definitely recommend this seller because it also arrived very quickly and well ahead of schedule…. The shop I have do my work had installed the system for me and i tried ordering it through them and they had three suppliers who were all on back order if k wanted it but this seller even beat the price and i had it within a couple of days instead of driving around for weeks and not being able to put air in the bags and I also had a leak so i was scared of driving with them empty of air and thought I would end up pinching the bags or at least one but the fast delivery made it a non issue! Would definitely highly recommend this seller and the product is definitely a high end product and if you bought the firestone airbags; then you also know the quality of firestone so I don’t need to explain anymore for you because you obviously got it before choosing the firestone system
