A mechanic will typically verify the actual oil pressure using a mechanical gauge connected directly to the oil gallery. As the engine oil pressure rises, it acts against the diaphragm, moving a plunger that closes the electrical contacts.

Conversely, when pressure drops due to low oil volume, a leak, or pump failure, the spring pushes the plunger back to open the circuit. Maintaining the correct oil pressure ensures that critical moving parts, such as bearings and camshafts, receive a constant stream of lubrication and cooling.
Technical Specifications and Variations These components are not one-size-fits-all, as they are engineered to specific pressure thresholds and electrical configurations to match the requirements of different engines. Functionally, the switch operates through a simple yet robust mechanism involving a diaphragm and a calibrated spring.
