Viair's sealed pressure switches are designed for the toughest ambient conditions. This pressure switch is normally open. When the pressure drops below 165 psi in the tank, the pressure switch will close the circuit and provide power to the compressors. Once the system hits 200 PSI, the pressure switch will open the circuit and cut power to the compressor.
This Viair pressure switch does what it's supposed to, but it took a little longer to arrive than I anticipated. The pressure settings are accurate and it has a solid build quality. Just wish the shipping was faster, but I can't complain about the product itself; it’s doing its job well.

Solid pressure switch for my compressor
I bought this Viair 90221 pressure switch for my air compressor, and it works great! It automatically turns on at 165 PSI and off at 200 PSI, just as expected. Installation was pretty straightforward, and I love how my compressor now runs efficiently without me having to monitor it constantly.

Stopped working after a few weeks
I really wanted to like the Viair 90221 switch; the specs seemed perfect for my needs. However, it stopped working after just a few weeks of use. I followed the installation instructions carefully, but it seems like I got a faulty unit. Disappointed with the performance.
