Kleinn Automotive 2151 Heavy Duty Pressure Switch

Model 2151 Sealed 12-Volt Pressure Switch- On: 110 PSI- Off: 145 PSI - 1/4" NPT Optimize your onboard air system with the Kleinn 2151 heavy-duty sealed air pressure switch, engineered with insulated wire leads to automatically turn your air compressor on at 110 PSI and off at 145 PSI with a standard 5 percent variance tolerance. Perfectly matched for use with Kleinn 6275RC, 6350RC, and 6450RC compressors, this universal 12-volt switch receives ignition power to efficiently signal a required SPDT 30-amp relay (such as Kleinn Model 340) to automate your pneumatic system under a 20-amp maximum load. For ultimate equipment protection against switch failure and to prevent costly compressor burnout, it is highly recommended to pair this unit with a 175 PSI safety relief valve (Kleinn SKU 52175) installed directly on your air tank. 20 amp max load The use of a relay is recommended (Kleinn model 340) Note: 5% tolerance standard Non-polarized wires (Ignition 12v input, 12v Output to Relay) Sealed 1/4" NPT Pressure Switch
