The MMTC 1KXL-O is an exterior hold open/close key switch designed for commercial gate and access control systems. Its maintained hold open/close operation provides controlled keyed activation for compatible automated gates, doors, and entry management applications.
This model includes a mortise cylinder and is intended for exterior flush-mount installations requiring secure keyed control. The 1KXL-O is part of MMTC’s commercial key switch lineup for professional access control environments. Manufacturer and distributor listings did not consistently publish detailed electrical ratings, enclosure specifications, or exact dimensions, so those details should be verified before installation.
