Camden CM-1110 Key Switch, SPST Maintained

Put security where you need it most: the Camden CM-1110 Key Switch from Camden Door Controls delivers a compact, durable way to control access and signal functions across commercial and industrial sites. This maintained SPST key switch accepts standard mortise cylinders (1"–1 1/4") for straightforward master-key compatibility, and its heavy-duty 1/4" aluminum plate plus one-piece die-cast construction provide dependable indoor/outdoor performance. The narrow mullion-style footprint (1 3/4" wide) conserves space on doorframes and works cleanly alongside surveillance and monitoring equipment for coordinated access control and alarm signaling.

Designed for installers and security managers, the CM-1110 integrates easily with existing wiring and control systems to minimize downtime and ensure reliable switching. Its maintained action keeps circuits engaged until intentionally released—making it ideal for controlled entry points, gate operation, or emergency override scenarios. The tamper-resistant build and commercial-grade materials reduce service calls and extend lifecycle value.
