Kleinn Air Horns 2151 150-PSI Sealed Pressure Switch with Lead Wires

Great pressure switch for my air horn system. Make sure you buy the correct On and Off pressure values. I also recommend not running the compressors power though this pressure switch, (although the gauge of the wires seem to indicate you could), I run my compressor power though a high amperage relay that this pressure sensor triggers.

I purchased this pressure switch to replace the broken one on my Kleinn HK7 train horn's air tank, it fit my model and works as expected. But after only 5 months the switch stopped working.

OUTSTANDING-PERFECT !

Works as it should

WORKS PERFECT, VERY NICE!

Didnt even last 6 months very disappointed
