Designed for access control and door activation applications, this push button is a staple component in commercial and institutional entry systems. Electricians and low-voltage security technicians install this device as part of exit device circuits, door release systems, and automatic door operator setups. The spring return mechanism ensures the contacts reset immediately upon release, making it suitable for momentary-trigger logic in access panels and control boards.\u003c\/p\u003e\n\u003cp\u003eThe CM-7020R\/3 is used in commercial door control applications where a reliable momentary switching device is required. Common installations include electric strike and magnetic lock release circuits, automatic door opener call stations, and egress push button stations. The dual NO\/NC contact output gives installers flexibility to wire for either a normally open or normally closed control loop without requiring additional hardware. This device is sold individually as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMomentary action with spring return — contacts reset immediately on release\u003c\/li\u003e\n  \u003cli\u003eDual-contact output: both normally open (NO) and normally closed (NC) available\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging — sold per each\u003c\/li\u003e\n  \u003cli\u003eSuited for exit device circuits, door release systems, and access control panels\u003c\/li\u003e\n  \u003cli\u003eLow-profile push button format for surface or gang-box mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation push button for commercial exit device and access control systems requiring a momentary, spring-return NO\/NC switch.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed electrician or low-voltage access control technician. De-energize the door control circuit and any connected electric hardware before wiring. Follow all applicable NEC guidelines for low-voltage control wiring and local AHJ requirements for egress and access control devices. Verify contact configuration (NO or NC) matches the logic requirements of the connected control board before commissioning.\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\u003eAction Type\u003c\/strong\u003e: Momentary, Spring Return\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Push Button\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Camden Door Controls Inc.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CM-7020R\/3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CAMDEN DOOR CONTROLS","offers":[{"title":"Default Title","offer_id":51563341873458,"sku":"CM-7020R\/3","price":181.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5786c14c495adfc884a35cd9bb51b033.jpg?v=1786495974","url":"https:\/\/voomisupply.com\/products\/camden-door-controls-cm-7020r-3-momentary-push-button","provider":"Voomi Supply","version":"1.0","type":"link"}
