This pressure switch monitors system pressure conditions and helps regulate compressor or circuit operation to maintain safe and reliable climate control performance in fleet and vocational environments.\u003c\/p\u003e\n\u003cp data-start=\"420\" data-end=\"858\"\u003ePressure switches play a critical role in HVAC and related vehicle systems by ensuring components operate only within proper pressure ranges. As original switches wear electrically, develop internal faults, or lose calibration, inaccurate pressure control and reduced system efficiency can occur. Replacing worn pressure switches helps restore proper pressure regulation, improve component protection, and reduce unplanned service events.\u003c\/p\u003e\n\u003cp data-start=\"860\" data-end=\"1280\"\u003eKEY FEATURES\u003cbr data-start=\"872\" data-end=\"875\"\u003e• Designed for heavy-duty truck HVAC and pressure monitoring applications\u003cbr data-start=\"948\" data-end=\"951\"\u003e• Helps regulate compressor or circuit operation based on system pressure conditions\u003cbr data-start=\"1035\" data-end=\"1038\"\u003e• Supports reliable system protection and consistent climate control performance\u003cbr data-start=\"1118\" data-end=\"1121\"\u003e• Durable construction suited for fleet, vocational, and on-highway use\u003cbr data-start=\"1192\" data-end=\"1195\"\u003e• Brand: Mack\u003cbr data-start=\"1208\" data-end=\"1211\"\u003e• Verify compatibility and application requirements before ordering\u003c\/p\u003e\n\u003cp data-start=\"1282\" data-end=\"1491\"\u003eTECHNICAL SPECIFICATIONS\u003cbr data-start=\"1306\" data-end=\"1309\"\u003eAlltrux Part Number: ATX910-1122\u003cbr data-start=\"1341\" data-end=\"1344\"\u003eOEM Reference: 20779171\u003cbr data-start=\"1367\" data-end=\"1370\"\u003eProduct Type: HVAC Pressure Switch\u003cbr data-start=\"1404\" data-end=\"1407\"\u003eBrand: Mack\u003cbr data-start=\"1418\" data-end=\"1421\"\u003eSystem Application: Heavy-Duty Truck HVAC \u0026amp; Pressure Control Systems\u003c\/p\u003e\n\u003cp data-start=\"1493\" data-end=\"1542\"\u003eCROSS REFERENCES\u003cbr data-start=\"1509\" data-end=\"1512\"\u003e20779171, 40PS48-1, 1MR2469M\u003c\/p\u003e\n\u003cp data-start=\"1544\" data-end=\"1658\"\u003eNote: Confirm OEM reference and application details before ordering to ensure proper fit and system compatibility.\u003c\/p\u003e","brand":"JX Peterbilt","offers":[{"title":"Default Title","offer_id":44154354860212,"sku":"ATX910-1122","price":48.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/7425\/5540\/files\/AC-Pressure-Switch-66055-Default__41216.1709652644.avif?v=1772483930","url":"https:\/\/parts.rodoc.com\/products\/atx910-1122-switch","provider":"Rodoc Leasing Sales \u0026 Service ","version":"1.0","type":"link"}
