Overview
Designed for reliable, commercial-grade access control, the Alarm Controls by ASSA ABLOY MCK-1-2 Mortise Cylinder Key Switch Station delivers secure, tamper‑resistant switching where dependable operator control is required. This SPDT alternate-action key switch toggles between open and closed states every key turn, making it ideal for door release, egress control and monitored entry points in security, surveillance and building automation systems. The stainless steel wall plate accepts standard 1-1/8" mortise cylinders (sold separately) and houses a compact switch with 1-1/4" depth behind the plate for clean, low-profile installations. Contacts rated 4A at 28 VDC support common locking hardware such as strikes and maglocks, while optional green/red LED indicators operate on 12 or 24 VAC/DC to provide instant visual status for installers and security staff. Tamper-proof and slotted screws are included, and a lifetime limited warranty ensures long-term peace of mind.
