AirCraft Pressure Switch SG-COMP06-31

At a Glance: Pre-wired pressure switch with threaded connection for automatic compressor start/stop control.

The AirCraft SG-COMP06-31 Pressure Switch is the “brain stem” of many compressor setups—monitoring pressure and telling the compressor when to switch on and off. When pressure drops to the cut-in point, it allows the compressor to start building pressure again; when the tank/system reaches the cut-out point, it switches off to help prevent over-pressurising. If your compressor is not starting, not stopping, cycling erratically, or struggling to maintain stable operation, a worn or faulty pressure switch is a common culprit. This AirCraft spare part is a practical replacement to restore dependable automatic control on compatible units.
