Pressure switches monitor refrigerant pressure on both the high and low sides of the refrigerant circuit, cutting power to the compressor if pressure falls outside safe operating limits. When either switch fails, the system will typically lock out immediately or refuse to start, protecting the compressor from catastrophic damage caused by low refrigerant, blockages, or overcharge conditions.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Part 312926-252 — High Side Pressure Switch | Part 312926-258 — Low Side Pressure Switch | Factory-calibrated trip points | Spade terminal connectors | Direct OEM replacement with no modifications required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are factory-calibrated to exact trip-point specifications for the CH13NA04800GAAAA.
