This single-pole, single-throw (SPST) switch monitors negative pressure generated by the inducer motor during the combustion cycle. When proper draft pressure is confirmed, the switch closes to allow ignition to proceed. HVAC technicians install and replace this switch as part of routine furnace service or when diagnosing inducer or venting faults. The single-port design connects to one pressure sensing tap on the inducer housing or condensate assembly.\u003c\/p\u003e\n\u003cp\u003eThis pressure switch is specifically used on the G7SC-1 Upflow\/Horizontal Furnace configuration. It is suited for residential forced-air gas furnace installations where the appliance is oriented in an upflow or horizontal position. Technicians servicing furnaces in tight utility closets, attic installations, or horizontal crawlspace applications will encounter this configuration regularly. Always confirm the setpoint and port count match the original switch before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.80 inches WC setpoint for accurate draft pressure proving\u003c\/li\u003e\n  \u003cli\u003eSPST switching configuration for straightforward circuit integration\u003c\/li\u003e\n  \u003cli\u003eSingle-port design for direct connection to inducer pressure tap\u003c\/li\u003e\n  \u003cli\u003eCompatible with G7SC-1 Upflow\/Horizontal Furnace application\u003c\/li\u003e\n  \u003cli\u003eFunctions as a safety interlock to prevent ignition without confirmed draft\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on the G7SC-1 Upflow\/Horizontal Furnace as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed HVAC technician should perform this replacement in compliance with local mechanical codes and the appliance manufacturer's service instructions. Disconnect power to the furnace and shut off the gas supply before removing the existing switch. Verify the pressure port tubing is free of cracks, moisture blockage, or debris before connecting the new switch. Do not bypass or jumper a pressure switch as a diagnostic shortcut in a live system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Setpoint\u003c\/strong\u003e: 0.80 inches WC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: SPST (Single-Pole, Single-Throw)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Configuration\u003c\/strong\u003e: Single Port\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: G7SC-1 Upflow\/Horizontal Furnace\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: 632495R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284005060914,"sku":"632495R","price":36.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277888.jpg?v=1781065764","url":"https:\/\/voomisupply.com\/products\/westinghouse-632495r-furnace-pressure-switch-0-80-in-wc-spst","provider":"Voomi Supply","version":"1.0","type":"link"}
