Overview
Secure critical entry points and streamline access control with the Alarm Controls by ASSA ABLOY MCK Series mortise key switch. This single‑gang mortise cylinder station delivers tamper‑resistant, professional control for security, surveillance and monitoring applications—ideal for server rooms, supply closets, and restricted areas. The stainless steel wall plate accepts standard 1-1/8" mortise cylinders (sold separately) and includes tamper‑proof screws for added protection. With contacts rated at 4A @ 28 VDC and alternate-action switching (selectable SPDT/DPDT models available), the MCK-1-4 integrates reliably with alarm panels, door controllers and access control systems. LED status options operate on 12/24 VAC/VDC to provide visible confirmation of lock/unlock or system state, while the shallow 1-1/4" switch depth eases installation in existing boxes. Optional pneumatic time delay and weather‑resistant cover expand its use to timed egress and outdoor or semi‑exposed mounting. Specify the MCK-1-4 to give technicians and security managers a rugged, easy-to-integrate key switch that enhances control and monitoring across your facility. Order today to add a durable, industry‑grade key switch to your access control hardware.
