5WG1221-2DB33 KNX Pushbutton Single With Status LED Aluminum Metallic i-System UP 221/33
The 5WG1221-2DB33 (UP 221/33) combines the aluminum metallic premium finish with an integrated status LED for visual state feedback. This single-gang KNX pushbutton mounts onto a BTM bus coupling unit via the PEI connector, and the status LED provides both load-state indication and optional orientation lighting in dark conditions.
The aluminum metallic surface suits modern interiors where tactile and visual elegance are priorities. Full ETS parametrisation provides per-button assignment to switching, dimming, blind, value, or scene functions, with the LED behaviour configurable independently.

Ideal for luxury residential and hospitality installations where both aesthetics and functionality are non-negotiable. The combination of aluminum metallic finish and LED feedback is particularly effective in master-switch positions – for example, a hotel room's main entry panel that controls and displays the state of all lighting circuits.
The LED orientation function assists navigation in cinema rooms, bedrooms, and corridors after dark. Compatible with the full DELTA i-system frame range for coordinated multi-gang assemblies.
