This switch monitors differential air pressure within HVAC systems and actuates an electrical circuit when pressure crosses the set point. It is used to verify airflow, detect blocked filters or flue obstructions, and protect equipment from operating outside safe pressure parameters. Licensed HVAC technicians install this device as part of furnace, air handler, and ventilation system control circuits.\u003c\/p\u003e\n\u003cp\u003eThis switch kit is suited for residential and light commercial HVAC applications where a single-pole double-throw pressure sensing device is required. The adjustable set point allows one part to cover a range of installations and system configurations. Typical uses include proving inducer draft, monitoring supply or return air pressure, and serving as a safety interlock within low-voltage control circuits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable sensing range of 0.25 to 1.0 inches water column (WC)\u003c\/li\u003e\n  \u003cli\u003eSPDT switching action provides both normally open and normally closed circuit paths\u003c\/li\u003e\n  \u003cli\u003eUniversal kit design covers a broad range of residential and light commercial HVAC applications\u003c\/li\u003e\n  \u003cli\u003eServes as a safety interlock for inducer draft proving and airflow verification\u003c\/li\u003e\n  \u003cli\u003eKit format includes switch and associated mounting or connection components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a universal OEM-style replacement air pressure sensing switch for residential and light commercial HVAC systems requiring an adjustable SPDT differential pressure switch in the 0.25 to 1.0 inches WC range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified HVAC technician. Disconnect all power to the unit before servicing the control circuit or replacing any pressure switch. Tubing connections to the pressure ports must be secure and free of cracks or kinks that could affect sensing accuracy. Follow all applicable local codes and manufacturer wiring diagrams when connecting the SPDT terminals to the control board.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: SPDT (Single-Pole Double-Throw)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Sensing Range\u003c\/strong\u003e: 0.25 to 1.0 inches water column (WC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustment\u003c\/strong\u003e: Adjustable set point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Universal air pressure sensing\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: RSS495011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRANE","offers":[{"title":"Default Title","offer_id":51506545099058,"sku":"RSS495011","price":59.24,"currency_code":"USD","in_stock":false}],"url":"https:\/\/voomisupply.com\/products\/trane-rss495011-adjustable-air-pressure-switch-kit-spdt","provider":"Voomi Supply","version":"1.0","type":"link"}
