The oil pressure switch is normally "Closed." The switch changes from a "Closed" circuit to an "Open" circuit, on increasing pressure of 48 kPa (7 psig). The oil pressure switch changes from an "Open" circuit to a "Closed" circuit, on decreasing pressure, between 14 kPa (2 psig) and 28 kPa (4 psig).
