I messed up and ordered the wrong pressure range but it is a very nice switch. It started correctly and pressure was within a couple pounds. In my setup but I couldn't test the high end cutout. Not penalizing on rating for.my mess up. Rating 5 starts because I was impressed how close the the startup was. I had it at 92 psi and it started but didn't run at 88 using my high quality digital gauge. I will probably purchase the right pressure range if the same switch. Probably keep this for my another compressor if one of those switches fail.

This HornBlasters air pressure switch is top notch reliable, durable, works perfectly with my quad train horn set up from HornBlasters! Installation was a breeze and it performs exactly as expected. Porn blasters is the only place I trust for all my train horn gear. Great quality and service every time! These guys are the best in the business for what they do!

There's not much else to say then that this pressure switch was a great fit in my matching horn blaster's tank.Using a gauge, I was able to verify that this cuts off and starts up at practically the perfect timing according to the gauge reading, 110 PSI on,150 PSI off.

Pipe thread seal is included on 1/4" pipe fitting. 110psi on 150psi off. Sent with terminal and pipe thread protectors.

I'm not sure if the HornBlasters Air Pressure Switch - 1/4" NPT / 20 Amps is something special or not.The completion on Amazon is an ETL Recognized component, which this is not, and it's 10 bucks.https://www.amazon.com/Pressure-Switch-120-150-Thread-Compressor/dp/B0BC8YBGH2/ref=asc_df_B0BC8YBGH2?mcid=6057dad6fb56328c840199bbad7abae2&hvocijid=15606970907013468660-B0BC8YBGH2-&hvexpln=73&tag=hyprod-20&linkCode=df0&hvadid=721245378154&hvpos=&hvnetw=g&hvrand=15606970907013468660&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9032152&hvtargid=pla-2281435178538&th=1https://www.amazon.com/Pressure-Switch-120-150-Thread-Compressor/dp/B0BC8YBGH2/ref=asc_df_B0BC8YBGH2?mcid=6057dad6fb56328c840199bbad7abae2&hvocijid=15606970907013468660-B0BC8YBGH2-&hvexpln=73&tag=hyprod-20&linkCode=df0&hvadid=721245378154&hvpos=&hvnetw=g&hvrand=15606970907013468660&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9032152&hvtargid=pla-2281435178538&th=1This does work as specified though, and it saves space compared to most pressure switches

I'm using this switch to control the clutch on an engine driven air compressor. The cut in and cut out pressures are spot on, closes at 110 and opens at 150 psi. Experience has taught me that these types of switches are short lived when switching high currents, even well below their max rating, so use a relay if you want it to last.

The HornBlasters Air Pressure Switch is a high-performance component designed to control the activation of air horns or other air-powered devices in your vehicle. It is available in various pressure ranges (85-105 PSI, 90-120 PSI, 110-150 PSI, 145-175 PSI, 165-200 PSI) to cater to different air system needs. The switch has a 1/4" NPT thread size and is rated for 20 amps, making it a suitable choice for a variety of air horn setups. Below is a detailed review based on its features, functionality, and overall performance.1.
