Camden CM-3230 Key Switch SPDT Maintained
Overview
The CM-3230 is a single pole, double throw (SPDT) key-operated switch rated 30VDC in maintained (spring-return) operation. It installs into standard 1", 1 1/8", or 1 1/4" mortise cylinders on a double-gang stainless steel faceplate — designed for flush mounting in doors or walls where authorized personnel need secure key-based override or supplemental control of door strikes, electromagnetic locks, or relay circuits. Built for indoor or outdoor use in access control installations that require tamper resistance and durable construction.
Compatibility
The CM-3230 pairs with standard mortise cylinder locks (sold separately) and 30VDC door control circuits found in most security integrator installations. It does not integrate with card readers, biometric systems, or networked access control panels directly — it is a wired switch device for manual key activation of strike release, lock sequencing, or auxiliary circuit signaling. Compatible with any access control system that accepts a 30VDC momentary or maintained contact closure (e.g., relay inputs on access control panels, strike controllers, electromagnetic lock power supplies). Confirm your panel supports 30VDC switching before ordering.
Installation Notes
The assembly includes a heavy-duty double-gang stainless steel faceplate with locators that prevent cylinder spinning — no set screws required. Package includes brass cylinder lock rings, 4 socket/slotted screws, 4 tamperproof screws with driver, and color-coded 18 AWG soldered leads with heat-shrink protective sleeves over contacts. Accepts up to two mortise cylinders per assembly, supporting left and/or right key operation. Mortise cylinders are not included; source separately to match your keying system. UL/CSA approved for both indoor and outdoor flush applications.
