The MMTC HBF is an interior OPEN/CLOSE key switch designed for commercial gate and access control systems. Its center-return keyed OPEN/CLOSE operation provides dependable control for compatible automated gates, doors, and entry management applications.
This model features a single gang flush-mount configuration and includes a mortise cylinder for secure keyed functionality.

Manufacturer and distributor listings did not consistently publish detailed electrical ratings or exact dimensions, so those details should be verified before installation.
