Alarm Controls MCK-6-5 MCK Series Mortise Cylinder Key Switch Station, Pneumatic Time Delay, Single Gang, Green/Red LED

Engineered for reliable access control and facility security, the Alarm Controls MCK-6-5 MCK Series mortise key switch station provides timed, tamper-resistant control where predictable activation is critical. Designed for commercial security and surveillance environments, this single-gang key switch uses a pneumatic time delay to ensure consistent momentary operation, minimizing accidental or prolonged door release. The stainless steel wall plate accepts standard 1-1/8" mortise cylinders (compatible with CY-1 and CY-1A) for quick replacement and seamless integration into existing systems.

Status LEDs (green/red) operate on 12 or 24 volts AC or DC for easy panel monitoring and visual confirmation at a glance, and the switch contacts are rated 4A @ 28VDC to drive locks, relays, and auxiliary security equipment reliably. Tamper-proof and slotted head screws are included for secure installation in corridors, server rooms, entrance control points, and surveillance hubs. Ideal for integrators and facilities managers looking for durable, easy-to-monitor key switch stations for access control and monitoring applications.
