It opens at 405 psi and closes at 300 psi, providing automatic high-side pressure protection for the compressor and refrigerant system. When refrigerant pressure rises beyond the 405 psi threshold, the switch interrupts the control circuit, stopping compressor operation before damage occurs. Once pressure drops back to 300 psi, the switch resets and allows normal operation to resume. This type of pressure control is a standard safety component in split systems, package units, and light commercial refrigeration equipment. Installation is typically performed by a licensed HVAC technician.\u003c\/p\u003e\n\u003cp\u003eThe SWT01719 is used in Trane HVAC central air systems as part of the high-side refrigerant pressure safety circuit. It is positioned on the high-pressure side of the refrigerant loop, typically near the compressor discharge line or liquid line service valve area. This switch protects the system from conditions such as condenser coil restriction, overcharge, or loss of condenser airflow that would cause abnormally high discharge pressures. It is suited for residential and light commercial applications where Trane OEM pressure control components are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOpens at 405 psi to interrupt the compressor control circuit under high-pressure conditions\u003c\/li\u003e\n  \u003cli\u003eCloses at 300 psi to restore normal operation once pressure returns to safe levels\u003c\/li\u003e\n  \u003cli\u003eOEM Trane part for accurate fitment and reliable performance in Trane refrigerant systems\u003c\/li\u003e\n  \u003cli\u003eFunctions as a compressor safety device on the high side of the refrigerant circuit\u003c\/li\u003e\n  \u003cli\u003eSuitable for residential and light commercial central air and package unit applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement high-pressure switch for Trane HVAC central air systems and accessories requiring a 405 psi open and 300 psi close pressure control switch.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with local codes and EPA Section 608 refrigerant handling regulations. Recover refrigerant and depressurize the high-side circuit before removing the existing switch. Ensure the replacement switch is rated for the refrigerant type and pressure range in the system. Restore refrigerant charge and verify switch operation before returning the unit to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpen Pressure\u003c\/strong\u003e: 405 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClose Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: High Pressure Cutout\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: HVAC Refrigerant Circuit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TRANE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SWT01719\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRANE","offers":[{"title":"Default Title","offer_id":51233230717234,"sku":"SWT01719","price":62.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307616826.gif?v=1780094839","url":"https:\/\/voomisupply.com\/products\/trane-swt01719-high-pressure-switch-405-psi-open-300-psi-close","provider":"Voomi Supply","version":"1.0","type":"link"}
