The LiftMaster 30-111-2 Push Button, Black is an original OEM replacement button used in select LiftMaster (Chamberlain) control stations for commercial door operators and vehicular gate operators. It restores the designated black-button function in a wall-mounted or enclosure-mounted station, allowing reliable manual control of the operator as defined by the station’s wiring and the operator’s control logic. This replacement part is intended for use on the operator’s low-voltage control circuit and is a practical solution when the existing button becomes worn, damaged, or unresponsive.
Compatibility is model-specific, so confirm that part number 30-111-2 appears in your operator manual or parts diagram before ordering. Installation typically involves disconnecting power, removing the original button from the control station, and transferring the control wires to the same labeled terminals on the new button in accordance with the operator’s wiring schematic. No programming is required; the function is determined by how the station is wired to the operator. For safety and code compliance (e.g., UL 325 and local regulations), installation and testing should be performed by a qualified door or gate technician.
