The MMTC HBFS is a flush mount tamperproof keyswitch designed for commercial and industrial access control systems requiring OPEN, CLOSE, and STOP functionality. Built for interior applications, the HBFS features a tamper-resistant enclosure with a stainless steel faceplate and includes a mortise cylinder for secure keyed operation in controlled-access environments.
This single gang control station is commonly used with automated doors, overhead door operators, and gate systems requiring secure manual control capability. Available manufacturer specifications identify the HBFS as a NEMA 1 rated interior device designed to fit standard single gang back boxes. Public listings also reference a center return keyswitch configuration and integrated STOP push button for commercial access applications.
