Upgraded Central Pneumatic Air Compressor Pressure Switch Control Valve: Replacement Parts for 90-120 PSI, 240V Air Compressor Review

As others have said there are no screw holes for the ground wire, be prepared to either drill and tap or use a small self tapping screw. The plastic lid differs from the original. So if you just want a lid, this won't work. The electrical contacts are smaller, so most likely they won't last long. The aluminum body is not as thick and durable as the original.
