Vixen Horns 120-150 PSI Air Pressure Switch Tank Mount Type 1/4" NPT 12V/24V for Train/Air Horn VXA7150

Worked to fix a compressor that ran until the pop off valves opened. I’m happy. New update June 23 2019. This worked for about 6 months and now it’s doing what this was supposed to fix. It runs until a 185 psi pop off switch opens. It failed to turn off the pressure reached through the primary side of a relay controlled air compressor.

I bought this to replace the 90 to 120 pressure regulator switch that came with my original air system. I simply removed the old one and installed this one along with a new PRV and everything worked perfectly

Worked great for about six months and then came apart ! I just got another one today and I hope it lasts longer . If not I’ll just have to find a different brand that will do the job .

Perfect. Everything works great and is loud as a blown ear drum. ^.^

I purchased this for my on board air system. It had a 200 psi max and I didn’t want to push the system that hard. This was a perfect fit. Keeps the psi just below 150psi. No more worries.
