Porter-Cable Z-D26612 Air Compressor Pressure Switch with an integrated unloader valve and lever is the replacement control for Porter-Cable air compressors. It automates the motor start/stop cycling by sensing tank pressure and switching the motor on at the cut-in pressure and off at the cut-out, while the unloader valve vents residual air from the pump head for easier startup. A manual lever provides optional start/stop control, and this unit is designed for Porter-Cable compressors that require the Z-D26612 switch.
