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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOn: 90 PSI - Off: 120 PSI\u003c\/li\u003e\n\u003cli\u003eNote: 5% tolerance standard\u003c\/li\u003e\n\u003cli\u003eThe use of a relay is recommended (Kleinn model 340)\u003c\/li\u003e\n\u003cli\u003e20 amp max load\u003c\/li\u003e\n\u003cli\u003eSealed 1\/4\" NPT Pressure Switch\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: Kleinn\u003c\/li\u003e\n\u003cli\u003ePart Number: 2121\u003c\/li\u003e\n\u003cli\u003eAdd-On: Use a 145 PSI Safety relief valve with this, SKU 52145.\u003c\/li\u003e\n\u003cli\u003eAttribute 1: On: 90 PSI\u003c\/li\u003e\n\u003cli\u003eAttribute 2: Off: 120 PSI\u003c\/li\u003e\n\u003cli\u003eAttribute 3: Note: 5% tolerance standard\u003c\/li\u003e\n\u003cli\u003eAttribute 4: The use of a relay is recommended\u003c\/li\u003e\n\u003cli\u003eAttribute 5: 20 amp max load\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eUniversal fit (not vehicle-specific).
