The high pressure switch is a refrigerant-side safety device that continuously monitors system operating pressure. When discharge pressure exceeds the rated cutout threshold, the switch opens the control circuit, shutting down the compressor to prevent catastrophic damage. A failed or weak switch will cause nuisance high-pressure lockouts, compressor short-cycling, or — if it fails in the closed position — allow dangerous over-pressurization events that can permanently damage the compressor.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at 406 PSI | Closes at 300 PSI | 1\/8\" NPT male connection | 240 VAC | SPST normally closed | Compatible with R-22 and R-410A refrigerant systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM switch manufactured to factory pressure tolerances.
