The HJ002800AV is an OEM Campbell Hausfeld pressure switch replacement designed for select Campbell Hausfeld portable air compressors. Listed in Campbell Hausfeld's replacement parts literature and cross-referenced to models such as HJ300400, this switch is sold as an authentic replacement for the factory component. The part number HJ002800AV identifies the switch and related fittings, and some listings describe it as "Pressure Switch Lefoo HJ002800AV," signaling an OEM-style switch used by Campbell Hausfeld.
