5WG1285-2DB12 KNX Pushbutton Single No Status LED Titanium White DELTA Style UP 285/12
The 5WG1285-2DB12 (UP 285/12) is a KNX single pushbutton panel designed in the classic DELTA style, finished in titanium white. With a larger 68 x 68 mm faceplate compared to the i-system series, the UP 285/12 suits environments where the traditional DELTA aesthetic is preferred or where retrofit compatibility with existing DELTA back boxes is required.
One horizontally arranged pair of rockers provides single-channel KNX control for lighting, blinds, HVAC, scenes, or value sending. No status LED is fitted, keeping the panel surface clean and unobtrusive. The device connects to a KNX BTM bus coupling unit via the physical external interface (PEI) and is fully configured through ETS software.

The UP 285/12 is the entry-level single-channel control point for DELTA style KNX installations. Its 68 mm format is immediately recognisable and compatible with the extensive installed base of DELTA back boxes and frame systems across Europe and Asia.
Typical uses include corridor light switching, individual room entry panels, and single-circuit blind control in residential apartments and commercial offices. The clean, LED-free faceplate suits spaces where discreet, unobtrusive controls are specified. Its BTM-based architecture allows future function changes via ETS reprogramming without any rewiring.
