Camden CM-1120 Key Switch, SPDT, N/O and N/C Momentary

Designed for secure, dependable access control in outdoor and high‑use environments, the Camden Door Controls CM-1120 Key Switch combines rugged construction with versatile operation. This CM-1100 series key switch accepts standard mortise cylinders (1", 1-1/8" or 1-1/4") and features SPDT momentary action with both N/O and N/C contacts, providing clear, programmable inputs for access control panels, security systems, surveillance monitoring and alarm integration. The one-piece 1/4" thick die-cast aluminum faceplate and weather-resistant utility box deliver vandal-resistant, corrosion-resistant protection for perimeter doors, gates and entry kiosks. Built with heavy-duty 6A contacts and cylinder locators that prevent spinning, the CM-1120 minimizes false activations and reduces maintenance downtime.
