The MMTC 3BX 3-Button Exterior Surface Mount Wall Control Station is a rugged, outdoor-rated Open/Close/Stop wall station designed for commercial and industrial door and gate operators. Intended for exterior installations, it provides simple, reliable control of overhead doors, rolling grilles, shutters, dock doors, and slide/swing gate operators from a convenient, clearly labeled three-button interface. As a universal replacement or upgrade, the 3BX is commonly used when a weather-resistant, surface-mount station is needed for everyday operation in warehouses, loading docks, parking facilities, and similar high-traffic environments.
This control station uses dry-contact switching, allowing it to interface with most operator brands that accept Open, Close, and Stop inputs at their control terminals, typically without requiring separate power to the station itself. Open and Close functions are momentary for precise positioning, while the Stop function provides an immediate interruption of motion for added safety. Installation involves standard low-voltage or control-circuit wiring to the operator’s terminal strip per the operator manufacturer’s instructions, and should be performed by a qualified technician following local codes and safety practices. The exterior-ready enclosure helps protect the controls from weather and jobsite conditions, making the MMTC 3BX a dependable choice for commercial/industrial applications requiring a durable, universal three-button wall station.
