This normally open (N.O.) high pressure switch monitors refrigerant system pressure and helps protect the compressor and related components by interrupting operation when pressure exceeds safe limits, supporting reliable climate control performance in fleet and vocational environments.\u003c\/p\u003e\n\u003cp data-start=\"508\" data-end=\"953\"\u003eHigh pressure switches play a critical role in HVAC system protection by preventing compressor damage caused by excessive refrigerant pressure. As original switches wear electrically, lose calibration, or develop internal faults, inaccurate pressure monitoring and reduced HVAC reliability can occur. Replacing worn high pressure switches helps restore proper pressure protection, improve system safety, and reduce unplanned HVAC service events.\u003c\/p\u003e\n\u003cp data-start=\"955\" data-end=\"1390\"\u003eKEY FEATURES\u003cbr data-start=\"967\" data-end=\"970\"\u003e• Designed for heavy-duty truck HVAC refrigerant pressure protection applications\u003cbr data-start=\"1051\" data-end=\"1054\"\u003e• Normally open (N.O.) high pressure switch helps protect compressor from overpressure conditions\u003cbr data-start=\"1151\" data-end=\"1154\"\u003e• Supports reliable A\/C system operation and component protection\u003cbr data-start=\"1219\" data-end=\"1222\"\u003e• Durable construction suited for fleet, vocational, and on-highway use\u003cbr data-start=\"1293\" data-end=\"1296\"\u003e• Brand: International\u003cbr data-start=\"1318\" data-end=\"1321\"\u003e• Verify compatibility and application requirements before ordering\u003c\/p\u003e\n\u003cp data-start=\"1392\" data-end=\"1630\"\u003eTECHNICAL SPECIFICATIONS\u003cbr data-start=\"1416\" data-end=\"1419\"\u003eAlltrux Part Number: ATX912-1110\u003cbr data-start=\"1451\" data-end=\"1454\"\u003eOEM Reference: 1676787C1\u003cbr data-start=\"1478\" data-end=\"1481\"\u003eProduct Type: High Pressure A\/C Switch (Normally Open)\u003cbr data-start=\"1535\" data-end=\"1538\"\u003eBrand: International\u003cbr data-start=\"1558\" data-end=\"1561\"\u003eSystem Application: Heavy-Duty Truck HVAC \u0026amp; Air Conditioning System\u003c\/p\u003e\n\u003cp data-start=\"1632\" data-end=\"1662\"\u003eCROSS REFERENCES\u003cbr data-start=\"1648\" data-end=\"1651\"\u003e1676787C1\u003c\/p\u003e\n\u003cp data-start=\"1664\" data-end=\"1783\"\u003eNote: Confirm OEM reference and application details before ordering to ensure proper fit and HVAC system compatibility.\u003c\/p\u003e","brand":"JX Peterbilt","offers":[{"title":"Default Title","offer_id":44154354303156,"sku":"ATX912-1110","price":43.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/7425\/5540\/files\/Screenshot2026-03-01130915.png?v=1772388616","url":"https:\/\/parts.rodoc.com\/en-ca\/products\/atx912-1110-high-pressue-switch","provider":"Rodoc Leasing Sales \u0026 Service ","version":"1.0","type":"link"}
