Champion P14203A Pressure Switch With Unloader Valve And On Off Lever

The Champion P14203A pressure switch with unloader valve and on/off lever is a control component for air compressor systems, combining automatic pressure-sensing with manual override. It governs when the compressor motor starts and stops based on system pressure, while the built-in unloader valve vents residual air from the pump head at shutoff to ease restart, reduce starting torque, and smooth overall cycling. The on/off lever provides direct manual control when automatic cycling isn’t desired, giving a straightforward way to override operation during servicing or testing. Identified by part number P14203A, this Champion assembly integrates essential pneumatic and electrical functions in a compact, ready-to-install package that supports reliable operation of standard compressor setups.
