The Champion CC1019871 pressure switch with unloader is a 26-amp control switch designed for Champion RV-series air compressors, with a 140–175 psi switching range that triggers motor start and stop as tank pressure changes. It includes an integrated unloader valve to vent air from the compressor head for load-free starting and reduced startup current. The CC1019871 designation identifies this specific RV-series model, intended for applications that require a high-current 140–175 psi switch with an onboard unloader. Use cases include Champion RV-series systems where reliable automatic pressure control is needed for portable or shop air compressors built around Champion components.
