Campbell Hausfeld CW212600SJ Pressure Switch

Campbell Hausfeld CW212600SJ is a four-port pressure switch for air compressors that controls motor cycling by turning the compressor off at 125 psi and back on at 95 psi, maintaining tank pressure within the 95–125 psi range. It is marketed as a genuine Campbell Hausfeld replacement part, listed as a 4-port switch with 1/4-inch connections, a configuration commonly found in Campbell Hausfeld 95/125 psi switching products. The four ports accommodate standard 1/4-inch piping, enabling straightforward integration with typical compressor plumbing and making it a direct-replacement option for Campbell Hausfeld units that use the 95/125 psi switching range. This switch is designed to restore automatic on/off control and help prevent short cycling, a common cause of motor wear in compressors that rely on a 95/125 psi pressure band.
