Pressure Switch for Air Compressors

The PowerMate 034-0184RP is a replacement compressor pressure switch rated for 125 to 155 psi and 22 amps. It is designed for owners of compatible air compressors who need to restore automatic cut-in and cut-out control. The four-port body fits a range of workshop and job-site units.

Pressure Range and Electrical Capacity

The switch operates between 125 psi cut-in and 155 psi cut-out, handling typical shop air demands up to its 22-amp rating. It will not support compressors that require higher pressure settings or motors drawing more than 22 amps. Buyers needing a wider pressure band or higher current capacity should look elsewhere.

Four-Port Configuration and Brand Compatibility

This switch uses a four-port manifold and cross-references Grainger part numbers 41RC92, 41RC93, 41RC94, 41RC96, 41RC97 and 59YY32. It is listed as compatible with Dewalt, Industrial Air, Industrial Air Contractor, Porter Cable and Powermate compressors using the specified manufacturer part numbers.

Questions about this item

Will the 125-155 psi range and 22-amp rating match the motor on my older Dewalt or Porter Cable compressor?

The switch is rated 125 to 155 psi and 22 amps and is listed as compatible with Dewalt, Porter Cable, Industrial Air and Powermate models including Grainger numbers 41RC92, 41RC93, 41RC94, 41RC96, 41RC97 and 59YY32.

How can I verify the switch is operating correctly once installed?

After wiring, run the compressor and confirm it cuts in near 125 psi and cuts out near 155 psi on the tank gauge; the four-port manifold should show no air leaks at the connections.

Does the package include the unloader valve tubing and mounting hardware, or must I buy them separately?

The listing only describes the pressure switch itself — 125 to 155 psi, 22 amps, four ports — so any unloader tubing, fittings or mounting screws would need to be sourced separately.
