This type of switch is typically used as a position or status contact, sensing the open or closed state of an overhead door by mounting directly to the door rail assembly. Electricians and security or access-control technicians are the primary installers. The unit is sold individually and falls within the miscellaneous contacts product category, making it a common component in industrial, commercial, and residential overhead door control and monitoring circuits.\u003c\/p\u003e\u003cp\u003eThis switch is suited for overhead door rail installations where a discrete position contact is required. Typical applications include commercial roll-up doors, sectional overhead doors in warehouses or garages, and similar door assemblies where rail-mounted sensing is needed. The switch monitors door position and provides a contact signal to a connected control panel, alarm system, or door operator circuit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRail-mount design for direct attachment to overhead door track assemblies\u003c\/li\u003e\n\u003cli\u003eFunctions as a position or status contact for overhead door open\/closed sensing\u003c\/li\u003e\n\u003cli\u003eSold as a single unit per package\u003c\/li\u003e\n\u003cli\u003eSuitable for integration with door operators, alarm panels, or access-control systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation contact switch for overhead door rail assemblies requiring a rail-mounted position switch.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed electrician or a qualified access-control or door systems technician. Before servicing or replacing the switch, disconnect all power to the door operator and any connected control circuit. Secure the switch firmly to the rail per the door manufacturer's mounting requirements and verify proper contact actuation across the full range of door travel before restoring power. Local electrical codes, including applicable NEC requirements for low-voltage control wiring, should be followed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each (EA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category\u003c\/strong\u003e: Miscellaneous Contacts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GEORGE RISK INDUSTRIES INC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4701A-48\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GEORGE RISK INDUSTRIES INC.","offers":[{"title":"Default Title","offer_id":51710379786546,"sku":"4701A-48","price":211.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4151d98e56ba13277033dc697c19124b.jpg?v=1788466182","url":"https:\/\/voomisupply.com\/products\/george-risk-industries-inc-4701a-48-rail-mount-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
