This single-pole, single-throw normally open (SPST NO) switch monitors airflow pressure through a dual-port configuration, confirming that the blower is operating before allowing the system to proceed through its control sequence. It is rated at 0.10 inches water column (WC) and is typically installed by licensed HVAC technicians during maintenance, troubleshooting, or component replacement on residential and light commercial cooling equipment.\u003c\/p\u003e\n\u003cp\u003eThe 632445R is intended for air conditioner applications where blower airflow verification is required as part of the system safety and operational sequence. A dual-port design allows the switch to sense differential pressure, making it appropriate for systems that require confirmed airflow before enabling downstream components. This part is suited for HVAC technicians servicing split-system or packaged air conditioning units that rely on pressure-activated interlocks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSPST NO configuration opens or closes circuit based on blower pressure threshold\u003c\/li\u003e\n  \u003cli\u003eDual-port design enables differential pressure sensing for accurate airflow detection\u003c\/li\u003e\n  \u003cli\u003eRated at 0.10 inches WC for precise low-pressure switching\u003c\/li\u003e\n  \u003cli\u003eDesigned as a direct replacement component for air conditioner blower pressure switch applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement blower pressure switch for air conditioner systems requiring a 0.10 WC SPST NO dual-port configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Disconnect all power to the unit at the disconnect box and verify the system is de-energized before removing or installing the switch. Ensure all pressure tubing connections are secure and free of cracks or kinks before restoring power. Work should comply with applicable local mechanical codes and manufacturer service procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: SPST NO (Single-Pole Single-Throw Normally Open)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 0.10 inches WC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Configuration\u003c\/strong\u003e: Dual Port\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Conditioner Blower\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: WESTINGHOUSE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 632445R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284081377586,"sku":"632445R","price":36.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277904.jpg?v=1781068043","url":"https:\/\/voomisupply.com\/products\/westinghouse-632445r-blower-pressure-switch-0-10-wc","provider":"Voomi Supply","version":"1.0","type":"link"}
