This binary pressure switch monitors refrigerant system pressure and helps protect the compressor and related components by cycling the system on or off when pressure thresholds are reached, supporting reliable climate control performance in fleet and vocational environments.\u003c\/p\u003e\n\u003cp data-start=\"500\" data-end=\"941\"\u003eBinary A\/C pressure switches play a critical role in HVAC system protection by preventing compressor operation under unsafe low or high pressure conditions. As original switches wear electrically, develop internal faults, or lose calibration, HVAC performance and compressor reliability can be affected. Replacing worn binary switches helps restore proper pressure monitoring, improve system safety, and reduce unplanned HVAC service events.\u003c\/p\u003e\n\u003cp data-start=\"943\" data-end=\"1369\"\u003eKEY FEATURES\u003cbr data-start=\"955\" data-end=\"958\"\u003e• Designed for heavy-duty truck HVAC and air conditioning pressure monitoring applications\u003cbr data-start=\"1048\" data-end=\"1051\"\u003e• Binary pressure switch helps protect compressor from low and high pressure conditions\u003cbr data-start=\"1138\" data-end=\"1141\"\u003e• Supports reliable A\/C system operation and component protection\u003cbr data-start=\"1206\" data-end=\"1209\"\u003e• Durable construction suited for fleet, vocational, and on-highway use\u003cbr data-start=\"1280\" data-end=\"1283\"\u003e• Brand: Volvo\u003cbr data-start=\"1297\" data-end=\"1300\"\u003e• Verify compatibility and application requirements before ordering\u003c\/p\u003e\n\u003cp data-start=\"1371\" data-end=\"1587\"\u003eTECHNICAL SPECIFICATIONS\u003cbr data-start=\"1395\" data-end=\"1398\"\u003eAlltrux Part Number: ATX922-1211\u003cbr data-start=\"1430\" data-end=\"1433\"\u003eOEM Reference: 1MR-3550M\u003cbr data-start=\"1457\" data-end=\"1460\"\u003eProduct Type: Binary A\/C Pressure Switch\u003cbr data-start=\"1500\" data-end=\"1503\"\u003eBrand: Volvo\u003cbr data-start=\"1515\" data-end=\"1518\"\u003eSystem Application: Heavy-Duty Truck HVAC \u0026amp; Air Conditioning System\u003c\/p\u003e\n\u003cp data-start=\"1589\" data-end=\"1619\"\u003eCROSS REFERENCES\u003cbr data-start=\"1605\" data-end=\"1608\"\u003e1MR-3550M\u003c\/p\u003e\n\u003cp data-start=\"1621\" data-end=\"1740\"\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":44154354630836,"sku":"ATX922-1211","price":65.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/7425\/5540\/files\/FSW-5402_01_lg.webp?v=1772401254","url":"https:\/\/parts.rodoc.com\/products\/atx922-1211-switch","provider":"Rodoc Leasing Sales \u0026 Service ","version":"1.0","type":"link"}
