Camden CM-1100 Key Switch, SPST Momentary N/O

For secure, vandal-resistant momentary control of doors and entry points, the Camden Door Controls CM-1100 key switch is a dependable choice for access control and security professionals. This flush-mount key switch features a heavy-duty 1/4" cast aluminum faceplate and one-piece die-cast construction that resists tampering and stands up to indoor or outdoor use. The CM-1100 uses SPST momentary (N/O) switch action, making it ideal for triggering electric strikes, automatic doors and integration with broader security and surveillance or monitoring systems.

Installation is straightforward: the unit accepts standard 1"–1 1/4" mortise cylinders (cam sold separately), so you can pair it with existing keys and cores. Its narrow 1 3/4" mullion profile fits tight frame applications without sacrificing durability. Designed by Camden Door Controls, the CM-1100 balances rugged build quality with flexible compatibility—helping reduce maintenance and downtime while improving site security.
