Momentary key switches provide a brief, operator-controlled signal that triggers an electric door operator, magnetic lock release, or access control panel only while the key is held in position. The CM-1150 houses two independent SPDT switch contacts in a single unit, allowing it to serve multiple circuits or control functions simultaneously. This type of device is installed by licensed electricians, low-voltage technicians, and access control specialists working on commercial entry systems.\u003c\/p\u003e\u003cp\u003eThe CM-1150 is suited for commercial and institutional door control installations where keyed, authenticated operation is required. Typical applications include electric door operators, automatic sliding or swinging door systems, gate controllers, and magnetic lock bypass circuits. The dual SPDT contact configuration makes it a practical choice where simultaneous triggering of two independent circuits is required from a single key action, such as unlocking a door while simultaneously signaling an access control panel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual SPDT (Single Pole Double Throw) contact configuration for independent circuit control\u003c\/li\u003e\n\u003cli\u003eMomentary action ensures signal is active only while key is held, reducing unintended access risk\u003c\/li\u003e\n\u003cli\u003eKeyed operation restricts activation to authorized personnel\u003c\/li\u003e\n\u003cli\u003eCompact single-unit housing accommodates two switch functions\u003c\/li\u003e\n\u003cli\u003eSuitable for integration with electric door operators and access control panels\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation key switch for commercial access control and electric door operator systems requiring a dual SPDT momentary switching function.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician or credentialed low-voltage access control technician in accordance with applicable NEC requirements. De-energize all connected door operator circuits and access control panels before wiring or replacing this switch. Verify that the contact ratings of the CM-1150 are appropriate for the load circuits being controlled prior to installation. Follow the door operator or access control system manufacturer wiring diagrams when connecting the dual SPDT contacts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: Dual SPDT (Single Pole Double Throw)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuation Type\u003c\/strong\u003e: Momentary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Keyed\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-1150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CAMDEN DOOR CONTROLS","offers":[{"title":"Default Title","offer_id":51560548270386,"sku":"CM-1150","price":248.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/538a248def57fd017fe1f8d10fcdafd6.jpg?v=1786453651","url":"https:\/\/voomisupply.com\/products\/camden-door-controls-cm-1150-dual-spdt-momentary-key-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
