It provides both normally open (NO) and normally closed (NC) contact configurations, giving installers flexibility to wire the switch into a wide range of access control panels and electric hardware setups. The green mushroom button head is the standard color convention for exit and egress points, making it immediately recognizable to building occupants. This switch is installed by licensed electricians or access control technicians as part of a compliant door egress system.\u003c\/p\u003e\n\u003cp\u003eThe CM-4020GE is suited for interior door egress points in commercial, institutional, and light industrial environments. Typical installations include office entry doors, stairwell egress doors, and corridor access points where a reliable momentary contact switch is needed to release electric strikes, magnetic locks, or electrified hardware. Its dual NO and NC output makes it compatible with both fail-safe and fail-secure electric locking hardware configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMushroom-style green button head — standard color for exit and egress signaling\u003c\/li\u003e\n  \u003cli\u003eDual contact output: normally open (NO) and normally closed (NC) on a single unit\u003c\/li\u003e\n  \u003cli\u003eSupports both fail-safe and fail-secure electric locking hardware wiring configurations\u003c\/li\u003e\n  \u003cli\u003eSuitable for commercial and institutional access control door systems\u003c\/li\u003e\n  \u003cli\u003eSold as individual unit (each)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style exit push button for use with commercial access control panels and electric door hardware systems requiring a momentary contact egress switch.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed electrician or certified access control technician. Disconnect and lock out all power to the access control panel and associated door hardware before wiring. Follow NFPA 70 (NEC) requirements for low-voltage control wiring and local AHJ requirements for egress hardware. Verify that the selected NO or NC contact output matches the wiring requirement of the connected electric strike, magloc, or access control panel before energizing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: Normally Open (NO) and Normally Closed (NC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eButton Style\u003c\/strong\u003e: Mushroom head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: Green\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: Camden Door Controls\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CM-4020GE\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CAMDEN DOOR CONTROLS","offers":[{"title":"Default Title","offer_id":51563038867762,"sku":"CM-4020GE","price":220.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75da613810494f20c8813b5a71567ef5_73166534-cd61-47a1-a269-91889b8c2379.jpg?v=1786488809","url":"https:\/\/voomisupply.com\/products\/camden-door-controls-cm-4020ge-mushroom-exit-switch-no-nc","provider":"Voomi Supply","version":"1.0","type":"link"}
