Collection: Pressure Switches

A pressure switch is an essential part of any on board air system. These will turn the compressor off when it has filled the tank to the required pressure. Then it will turn the compressor on again as you use some of the air in the tank.
Please see the Tech Info link above to look at how these are fitted and wired up.

The pressure switches in this collection are not sealed. This means they are not really designed to be 'outside' in the weather.
We do have sealed pressure switches, here
