Review on Wadoy Replacement Pressure Switch Control Valve for Central Pneumatic Air Compressor Parts - 90-120 PSI, 240V by Antonio Santiago

I have a Central Pneumatic model 40400 air compressor. This unit is over 10 years old. When the pressure switch failed, Harbor Freight stated that they would no longer sell parts for that compressor. Although the new model of air compressor looks the same as the old model, it just has a different part number. This switch worked great as a replacement. The only problem is that two ground pins need to be drilled as two of the holes are too small for the standard equipment installed on the compressor.
