The Gira Universal Pushbutton Interface, 2-gang (1118 00), is a KNX interface designed to connect compatible external pushbuttons or contacts to a building automation system. Its two inputs allow external control points to be represented as KNX commands after configuration in ETS. This can help integrate conventional momentary switches or other supported contact devices into lighting and room-control schemes without replacing every field control with a dedicated KNX sensor. The exact supported functions depend on the product application and connected circuit type. Before installation, confirm input wiring, permitted cable and contact characteristics, supply requirements and accessory compatibility in the current Gira documentation. Use the correct ETS product database for commissioning.
