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.

Automatic Pressure Control You Can Trust: the SG-COMP06-31 Pressure Switch

Designed for compressor applications where reliable cut-in/cut-out control is essential for safety and performance. Match the Cat No. SG-COMP06-31 to your existing switch to ensure correct fitment and function.

Extra Information

  • Confirm compatibility: Match SG-COMP06-31 with your existing part and compressor model.
  • Check pressure ratings: Ensure the switch is suitable for your system’s operating pressure range.
  • Verify wiring: Confirm correct wire connections and insulation before powering up.
  • Inspect fittings for leaks: Use correct sealing methods on the threaded port and test after installation.

Pro Tip

  • If you’re replacing a pressure switch due to erratic cycling, also inspect for air leaks and check the non-return valve/unloader line (where fitted). A small leak can mimic switch problems and cause rapid cycling.

Features

  • Automatic cut-in / cut-out control Helps manage compressor cycling based on system pressure.
  • Threaded pressure port Designed to mount into the appropriate pressure connection point.
  • Pre-wired leads Simplifies installation and keeps wiring neat in the control area.
  • Compact, service-friendly design Ideal for maintenance and straightforward replacement by part number.

Benefits

  • Improves safety: Helps prevent over-pressurising by switching off at the correct point.
  • Restores reliable operation: Fixes common issues like failing to start/stop or unstable cycling.
  • Protects the compressor: More consistent switching can reduce strain and unnecessary wear.
  • Better efficiency: Helps the compressor run only when needed to maintain pressure.

Safety

  • Isolate and disconnect power before opening any electrical housing or replacing switches.
  • Depressurise the compressor/tank fully before removing the old pressure switch.
  • Wear eye protection when working around pressurised fittings and during leak testing.
  • Ensure wiring is correctly connected and insulated—incorrect wiring can cause damage or unsafe operation.
  • After installation, run a controlled test and confirm the compressor stops at the correct pressure and that there are no leaks.
