It operates on a single-pole double-throw (SPDT) switching configuration rated at 5 amps, making it suitable for a range of low-voltage control circuit applications. The concealed form factor allows the switch to be recessed into the door and frame, keeping the hardware hidden from view while maintaining reliable reed-switch operation. Installation is typically performed by security integrators, locksmiths, or access control technicians.\u003c\/p\u003e\n\u003cp\u003eThe MC-4 is used in commercial and residential door hardware applications where a discrete, flush-mounted magnetic contact is preferred over surface-mount alternatives. Typical scenarios include monitoring the open or closed status of doors in access control panels, alarm systems, and building automation systems. Its SPDT output provides both normally open and normally closed circuit paths, giving installers flexibility in how the switch integrates with the control system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConcealed mounting design keeps hardware hidden within the door and frame\u003c\/li\u003e\n  \u003cli\u003eSPDT switching provides both normally open and normally closed output paths\u003c\/li\u003e\n  \u003cli\u003e5 amp contact rating supports a broad range of control circuit loads\u003c\/li\u003e\n  \u003cli\u003eMagnetic actuation with no mechanical contact wear for long service life\u003c\/li\u003e\n  \u003cli\u003eSold individually as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style concealed magnetic switch for door position monitoring in access control, intrusion alarm, and building automation applications where a recessed SPDT magnetic contact is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified security or low-voltage technician following applicable local codes and manufacturer guidelines. De-energize all connected control circuits before installing or servicing the switch. Proper alignment between the magnet and the switch body is critical for reliable actuation; verify gap tolerances per the product manual before finalizing installation. Consult the SDC product manual for mounting dimensions and wiring diagrams specific to this model.\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\u003eContact Rating\u003c\/strong\u003e: 5 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Style\u003c\/strong\u003e: Concealed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\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: SDC - SECURITY DOOR CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MC-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SDC","offers":[{"title":"Default Title","offer_id":51687930724658,"sku":"MC-4","price":100.98,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/sdc-mc-4-concealed-magnetic-switch-spdt-5-amp","provider":"Voomi Supply","version":"1.0","type":"link"}
