The oil pressure warning light switch registers low oil pressure in the main oil gallery on the outflow side of the filter. While the engine is running and oil pressure is correct, the switch is open. When the ignition is switched on or if oil pressure drops below the pressure setting of the switch, the switch closes and the low oil pressure warning lamp located in the instrument pack will illuminate.
