The Campbell Hausfeld CW218800AV pressure switch is a replacement part for Campbell Hausfeld air compressors, rated for a 120–150 psi switching range. It automatically controls the compressor by turning the motor off at the upper pressure limit and back on as pressure falls, helping maintain steady output and protect the pump. Designed for Campbell Hausfeld units that operate within the 120–150 psi range, this CW218800AV component is used to regulate pressure up to 150 psi in hobbyist and shop compressors that require a reliable, automatic shut-off function.
