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.
