This oil pressure switch is commonly used on Porsche 912E, 914, 924, and various Volkswagen models including air-cooled and early water-cooled engines. The switch detects when oil pressure falls below the specified threshold and completes the electrical circuit to illuminate the warning lamp, helping prevent catastrophic engine failure due to insufficient lubrication.
