Magnetic contact switches of this type monitor the open or closed status of a door, window, or access panel by detecting the presence or absence of a paired magnet. When the magnet separates from the switch body, the loop opens and triggers the connected control circuit. This switch is suited for low-voltage alarm and access-control wiring work and is sold as a single unit.\u003c\/p\u003e\n\u003cp\u003eSurface mount magnetic contact switches are installed on the stationary frame of a door or window, with the magnet mounted on the moving sash or door edge. The closed-loop wiring configuration means the circuit is normally closed at rest and opens upon separation, which is the standard fail-safe topology used in intrusion detection, access control, and building automation panel wiring. The white finish allows the switch to blend with standard interior door and window trim in residential and light commercial installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClosed-loop wiring configuration for fail-safe intrusion detection and access control circuits\u003c\/li\u003e\n  \u003cli\u003eSurface mount design simplifies installation on door frames and window casings without routing\u003c\/li\u003e\n  \u003cli\u003eWhite finish suits standard residential and light commercial interior trim\u003c\/li\u003e\n  \u003cli\u003eSold as individual unit for single-point replacement or new installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for surface mount magnetic contact switch applications in residential and light commercial door and window alarm or access control systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed alarm technicians or low-voltage electricians in accordance with applicable local codes and NFPA 72 requirements where intrusion detection is involved. De-energize the control panel circuit before connecting or disconnecting switch wiring. Mount the switch body to the fixed frame and the magnet to the moving door or sash, aligning the two components within the manufacturer-specified gap for reliable operation. Verify loop continuity at the panel before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Surface mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoop Configuration\u003c\/strong\u003e: Closed loop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each (1 unit)\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: George Risk Industries Inc.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1100A-12-W\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GEORGE RISK INDUSTRIES INC.","offers":[{"title":"Default Title","offer_id":51685886230834,"sku":"1100A-12-W","price":22.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87d82112b97eef2631ca52c47fef10a8.jpg?v=1788220254","url":"https:\/\/voomisupply.com\/products\/george-risk-industries-1100a-12-w-surface-mount-contact-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
