It features two single-pole double-throw (SPDT) switching circuits in a maintained-action configuration, meaning the switch holds its position after the key is turned rather than returning to neutral on key removal. Licensed electricians and low-voltage technicians install this type of device to provide secure, key-operated control of electric door hardware, magnetic locks, electric strikes, and related access control equipment.\u003c\/p\u003e\n\u003cp\u003eThe CM-1160 is suited for commercial entry points, vestibule doors, stairwell egress doors, and secured interior access zones. Maintained keyswitches are a common choice when the controlled device must remain energized or de-energized until deliberately switched back, such as holding a mag-lock released during a loading operation or disabling a door access reader for maintenance. The dual SPDT output configuration allows simultaneous control of two independent circuit paths from a single key operation, supporting more complex access control wiring layouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaintained-action switching holds circuit state after key is turned and removed\u003c\/li\u003e\n  \u003cli\u003eDual SPDT contacts provide two independently switchable circuit paths\u003c\/li\u003e\n  \u003cli\u003eKey-operated actuation restricts control to authorized personnel\u003c\/li\u003e\n  \u003cli\u003eDesigned for integration with electric locks, strikes, and access control panels\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit (each)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style component for commercial access control systems requiring key-operated maintained switching at door entry points.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed electrician or certified low-voltage technician in accordance with applicable NEC requirements for access control wiring. De-energize all connected door hardware and access control panel circuits before wiring or replacing the keyswitch. Verify that the maintained switching mode is appropriate for the controlled device, as using a maintained switch in place of a momentary switch can result in unintended latch or lock states. Confirm correct circuit polarity and contact orientation before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: 2 SPDT Maintained\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAction\u003c\/strong\u003e: Maintained (key-retained position)\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-1160\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CAMDEN DOOR CONTROLS","offers":[{"title":"Default Title","offer_id":51563875991858,"sku":"CM-1160","price":249.1,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ea96c76c09935bdbe80a40936c4c5c9.jpg?v=1786505691","url":"https:\/\/voomisupply.com\/products\/camden-door-controls-cm-1160-keyswitch-2-spdt-maintained","provider":"Voomi Supply","version":"1.0","type":"link"}
