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.

Correct Cycling Starts Here: the SG-COMPSP-03 Comp 04 Pressure Switch

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.

Features

Automatic cut-in / cut-out control Manages compressor start/stop based on pressure levels.
Designed for Comp 04 Part-number matched replacement for the AirCraft Comp 04.
Pre-wired lead Simplifies installation and reduces wiring hassle.
Threaded pressure port Mounts into the correct pressure connection point (confirm thread size).

Benefits

Restores reliable operation: Fixes common faults like failure to start/stop or inconsistent cycling.
Improves safety: Helps prevent overpressure by switching off at the intended point.
Protects the compressor: More stable cycling can reduce strain and unnecessary wear.
Reduces downtime: Quick replacement solution when matched by part number.

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.
