In these applications the switch threads into the main oil gallery and closes its contact when oil pressure drops below the calibrated set-point (0.3–0.5 bar), triggering an immediate warning lamp and, on units so equipped, shutting down the engine to prevent catastrophic bearing or turbocharger failure.\u003c\/span\u003e\u003cbr\u003e\n\u003cbr\u003e\n\u003cspan style=\"font-size:16px;\"\u003eTechnical specifications:  \u003c\/span\u003e\u003cbr\u003e\n\u003cspan style=\"font-size:16px;\"\u003eThe switch is a single-pole, normally-closed pressure-actuated device housed in a zinc-nickel-plated steel body with 1\/8\" NPTF male thread and 19 mm hex, 48 mm overall length and 55 g mass. \u003c\/span\u003e\u003cbr\u003e\n\u003cbr\u003e\n\u003cspan style=\"font-size:16px;\"\u003eMaterial \u0026amp; performance features:  \u003c\/span\u003e\u003cbr\u003e\n\u003cspan style=\"font-size:16px;\"\u003eThe pressure-sensing diaphragm is phosphor bronze with a nitrile sealing disc, giving excellent resilience against vibration and thermal cycling.
