AirCraft Pressure Switch SG-COMPSP-03 For Comp 04
At a Glance: Pre-wired replacement pressure switch for AirCraft Comp 04—controls automatic start/stop based on system pressure.
The AirCraft SG-COMPSP-03 Pressure Switch is a dedicated replacement pressure control switch for the AirCraft Comp 04. Its job is to monitor pressure and manage the compressor’s automatic cycling: switching the compressor on when pressure drops (cut-in) and switching it off when the target pressure is reached (cut-out). If your Comp 04 is not starting, not stopping, or cycling erratically, a failing pressure switch is a common cause. Replacing it with the correct AirCraft part helps restore predictable, safe operation and keeps your compressor working the way it was designed to.
A healthy pressure switch protects the system from over-pressurising and keeps performance consistent. Match the Cat No. SG-COMPSP-03 to your Comp 04 for proper fitment and function.

Extra Info
Extra Information
- Compatibility: Intended for AirCraft Comp 04 (confirm with your parts list).
- Check wiring: Verify correct wire connections and ensure terminals are secure and insulated.
- Inspect for air leaks: A leaking system can cause rapid cycling that looks like switch failure.
- Seal the thread correctly: Use an appropriate thread seal where required and test for leaks after fitting.
Pro Tip
- If your Comp 04 is cycling too often, check for leaks at fittings and hoses before blaming the switch. Fixing a small leak can dramatically improve cycling behaviour and extend component life.
Safety
Safety
- Isolate and disconnect power before replacing any pressure switch.
- Depressurise the compressor/tank fully before removing the old switch.
- Wear eye protection when working around fittings and during leak testing.
- Ensure wiring is correctly connected and insulated to prevent faults or unsafe operation.
