Kleinn Automotive Accessories Model 2121 12-Volt Sealed Pressure Switch - On: 90 PSI - Off: 120 PSI - 1/4" NPT

Description:

The Kleinn Model 2121 is a premium sealed pressure switch engineered to automate your onboard air system by keeping tank pressure regulated between 90 PSI and 120 PSI. Optimized for use with the 6260RC air compressor, this heavy-duty switch features a standard 5% PSI variance tolerance and operates on 12-volt ignition power to signal a required SPDT 30-amp relay (Kleinn Model 340), safely turning the compressor on and off automatically. For maximum system protection, it is highly recommended to pair this switch with a 145 PSI safety relief valve (SKU 52145) installed on the air tank; in the event of a pressure switch failure, the safety valve will release a burst of air to alert you to cut power to the compressor, preventing a costly burn-out until the switch can be replaced.
