The Eelectron BK04MV-BR is the 4-button kit in metal bronze for the OL-U KNX switch SO08A01KNX (8 buttons, 16 channels, RGB swipe bar, thermostat). SO08A01KNX ships as bare hardware; the key set, a PO71 cover frame and an FO71A01 metal frame are ordered separately to suit the interior. This layout gives four full-width buttons, each key backed by its own RGB LED and freely programmable in ETS.
The finish is metal, bronze (MV-BR), one of the four 2026 additions to the OL-U Metal Edition beside the original silver (MT-SH); the MV code supersedes the earlier MT code for the coloured metals. The same tone runs across the BKxxMV-BR key sets and every PO-series frame format, so keypad, thermostat and adjacent receptacles can share one metal. Other tones: champagne (MV-CH), gold (MV-GO), black (MV-BK).
Key Features
- Layout: 4 buttons (one full-height button per row)

- Snap-on fit over the device, under the cover frame; individual keys lift out with a flat screwdriver
