Industrial VT412024 Air Compressor Pressure Switch

The VT412024 is a four-port, adjustable replacement pressure switch for air compressors, engineered to cycle between 95 and 125 psi so the motor starts and stops in response to the tank pressure and maintains a reliable air supply. As a RolAir VT-series compatible component, this switch is designed to be a direct replacement for OEM units, featuring an unloader port that releases residual air at shutoff to help the system reset and prepare for the next start. Its four-port configuration supports the standard piping layout found on many portable and industrial compressors, with dedicated lines for the tank, unloading, and the control of the auto-start function. Ideal for service, maintenance, or upgrades, the VT412024 provides precise cut-in and cut-out performance within the 95–125 psi range, making it a practical choice when a dependable, adjustable pressure switch is required to sustain steady air delivery.
