🔽 24V 12V Air Pressure Switch, 90-120 PSI, 1/4"-18 NPT, Compressor Pressure Switch Review

Works as expected. I use it for my makeshift onboard air compressor in my truck. I have this on the air manifold to the tank and it turns the air compressor on and off as the pressure drops and rises.

I've only used one of these so far. The construction is solid. The terminals are strong when connecting wires. Works as intended to keep the pressure on my system. Durability seems good, I'm sure they will survive life in my hot engine bay.

Installed these pressure switches on my air tank and hooked them up correctly. I started two compressors and one stopped working. Swapped the wires and found that a pressure sensor is no longer working. Now I run both compressors from the same switch and I don't like it.

Turning off the safety valve on my compressor before shutting down was enough to keep it from ever shutting down. I returned the first ones and bought a lower rated set and it works fine. I would recommend buying one that has a cut-off threshold of at least 15 pounds below your compressor's maximum pressure rating.
