Designed for access control and security applications, it provides a durable, corrosion-resistant switching point that remains latched in position until manually returned. The KR-2 is installed by licensed electricians and security system integrators in low-voltage control circuits where a keyed, tamper-resistant input is required. Its plate-style form factor fits standard single-gang electrical boxes, making it straightforward to integrate into new construction or retrofit projects.\u003c\/p\u003e\n\u003cp\u003eThe KR-2 is suited for commercial and light industrial access control installations, including entry points, elevator controls, door release circuits, and security panel inputs. The two N\/O contact outputs allow it to interface with a wide range of control systems, including door strikes, magnetic locks, alarm panels, and relay modules. Its stainless steel faceplate holds up in high-traffic or corrosive environments where standard finishes may degrade over time.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLatching key switch action holds position until key is rotated back\u003c\/li\u003e\n  \u003cli\u003eTwo normally open (N\/O) contacts for dual-circuit switching capability\u003c\/li\u003e\n  \u003cli\u003eStainless steel faceplate resists corrosion in demanding environments\u003c\/li\u003e\n  \u003cli\u003eSingle-gang plate format mounts to standard electrical boxes\u003c\/li\u003e\n  \u003cli\u003eKeyed operation prevents unauthorized switching\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 single-gang access control and exit device switch circuits in commercial and light industrial security systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician or qualified security systems integrator. Shut off all power to the control circuit before wiring the switch contacts. Follow applicable NEC guidelines for low-voltage wiring and enclosure fill. Verify contact ratings against the connected load before energizing the circuit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: 2 Normally Open (N\/O)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Action\u003c\/strong\u003e: Latching\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFaceplate Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Format\u003c\/strong\u003e: Single-Gang Plate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each (1 per 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: Alarm Controls Corporation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KR-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALARM CONTROLS","offers":[{"title":"Default Title","offer_id":51557285036338,"sku":"KR-2","price":466.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b018f3ea8e6f4280e20923ea639b5f63.jpg?v=1786385202","url":"https:\/\/voomisupply.com\/products\/alarm-controls-corporation-kr-2-latching-key-switch-2-n-o","provider":"Voomi Supply","version":"1.0","type":"link"}
