MARS 43335 Pressure Switch offering a robust mechanical sealThe MARS 43335 Pressure Switch is a high performance, fixed setting control engineered for demanding HVACR applications, particularly those utilizing R410A refrigerant. This high pressure cut out switch features a SPST (Single Pole Single Throw) normally closed contact configuration, calibrated to "open on rise" at 600 PSI cut out and automatically reset (cut in) at 475 PSI. Built with a tamper proof, hermetically sealed sensor, the 43335 ensures long
