This pressure switch monitors refrigerant system pressure and helps control compressor operation to maintain proper system performance and component protection in fleet and vocational environments.\u003c\/p\u003e\n\u003cp data-start=\"410\" data-end=\"839\"\u003ePressure switches play a critical role in HVAC system control by ensuring the compressor operates only within safe pressure ranges. As original switches wear electrically, develop internal faults, or lose calibration, inaccurate pressure readings and reduced HVAC reliability can occur. Replacing worn pressure switches helps restore proper system control, improve compressor protection, and reduce unplanned HVAC service events.\u003c\/p\u003e\n\u003cp data-start=\"841\" data-end=\"1243\"\u003eKEY FEATURES\u003cbr data-start=\"853\" data-end=\"856\"\u003e• Designed for heavy-duty truck HVAC refrigerant pressure control applications\u003cbr data-start=\"934\" data-end=\"937\"\u003e• Helps regulate compressor operation based on system pressure conditions\u003cbr data-start=\"1010\" data-end=\"1013\"\u003e• Supports reliable A\/C system performance and component protection\u003cbr data-start=\"1080\" data-end=\"1083\"\u003e• Durable construction suited for fleet, vocational, and on-highway use\u003cbr data-start=\"1154\" data-end=\"1157\"\u003e• Brand: Volvo\u003cbr data-start=\"1171\" data-end=\"1174\"\u003e• Verify compatibility and application requirements before ordering\u003c\/p\u003e\n\u003cp data-start=\"1245\" data-end=\"1454\"\u003eTECHNICAL SPECIFICATIONS\u003cbr data-start=\"1269\" data-end=\"1272\"\u003eAlltrux Part Number: ATX921-1150\u003cbr data-start=\"1304\" data-end=\"1307\"\u003eOEM Reference: 1MR2472M2\u003cbr data-start=\"1331\" data-end=\"1334\"\u003eProduct Type: A\/C Pressure Switch\u003cbr data-start=\"1367\" data-end=\"1370\"\u003eBrand: Volvo\u003cbr data-start=\"1382\" data-end=\"1385\"\u003eSystem Application: Heavy-Duty Truck HVAC \u0026amp; Air Conditioning System\u003c\/p\u003e\n\u003cp data-start=\"1456\" data-end=\"1486\"\u003eCROSS REFERENCES\u003cbr data-start=\"1472\" data-end=\"1475\"\u003e1MR2472M2\u003c\/p\u003e\n\u003cp data-start=\"1488\" data-end=\"1607\"\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":44154354663604,"sku":"ATX921-1150","price":65.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/7425\/5540\/files\/LSW-0967_02_lg.webp?v=1772483723","url":"https:\/\/parts.rodoc.com\/products\/atx921-1150-switch","provider":"Rodoc Leasing Sales \u0026 Service ","version":"1.0","type":"link"}
