Designed for special application contact installations, this unit mounts flush into door frames, walls, or structural members where a low-profile, concealed sensing point is required. The black finish integrates discreetly into dark-colored frames and housings. It is typically installed by licensed alarm and access control technicians or licensed electricians working on security, intrusion detection, or access monitoring systems where standard surface-mount contacts are not appropriate.\u003c\/p\u003e\u003cp\u003eThis switch is suited for commercial and residential special application installations where recessed mounting is required to maintain aesthetic or structural integrity. The three-switch, three-open-circuit configuration supports more complex wiring schemes than a standard single-circuit contact, making it appropriate for supervised loop architectures, multi-zone monitoring, or redundant sensing arrangements. It is sold as a single unit per package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRecessed mounting design for concealed, flush installation\u003c\/li\u003e\n\u003cli\u003eThree internal switches with three normally open circuits\u003c\/li\u003e\n\u003cli\u003eBlack finish for discreet integration into dark frames or surfaces\u003c\/li\u003e\n\u003cli\u003eSpecial application contact category, suited for non-standard sensing requirements\u003c\/li\u003e\n\u003cli\u003eSingle-unit packaging for straightforward procurement and replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install recessed magnetic contact switch for special application contact systems requiring a three-switch, three-open-circuit configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician or certified alarm and access control technician in accordance with applicable local codes and NFPA 731 guidelines. De-energize the circuit and verify zero voltage at the wiring terminals before handling or connecting any conductors. Recessed contact switches require precise boring or routing of the mounting cavity to ensure proper magnet-to-switch alignment and reliable actuation. Do not exceed the rated electrical parameters of the switch contacts during wiring.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: 1 Recessed Unit, 3 Switches, 3 Normally Open Circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Special Application Contacts\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 Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MAGNASPHERE CORP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSS-330C-BLACK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MAGNASPHERE","offers":[{"title":"Default Title","offer_id":51686961873202,"sku":"MSS-330C-BLACK","price":152.26,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/magnasphere-corp-mss-330c-black-recessed-magnetic-contact","provider":"Voomi Supply","version":"1.0","type":"link"}
