Campbell Hausfeld CW210700AV Pressure Switch 4 Port

Campbell Hausfeld CW210700AV pressure switch is a four-port, 1/4" NPT-equipped control for Campbell Hausfeld air compressors that automatically starts and stops the pump as tank pressure changes. It uses a 100 psi on and 135 psi off setting, so the compressor activates at 100 psi and shuts off at 135 psi to help maintain target pressure and protect the system from over-pressurization. The four-port configuration accommodates standard Campbell Hausfeld plumbing and wiring within a compact housing, simplifying installation and serving as a direct replacement for compatible CW210700AV units. Designed for Campbell Hausfeld compressors, this switch provides reliable cut-in/cut-out pressure control that regulates airflow and minimizes unnecessary cycling, contributing to consistent performance in hobby and shop applications.
