Brand: Auto Meter Gauges
This heavy-duty pressure switch from Auto Meter is normally on (NC) when no pressure is applied. It is designed to turn off when pressure rises above 50 psi. This makes it ideal for activating a warning light (not included) when oil or fuel pressure drops below 50 psi. 1/8 NPT male threads make it easy to install in most fluid systems.
The two-wire, non-grounding switch can be used with just about any warning light, including the Auto Meter Pro-Lite Warning Light, Part No. AM3240, and the Auto Meter Mini Pro-Lite Warning Light, Part No. AM3239 (each sold separately).
