Design and materials
A KNX switch with a flat black glass front and no frame. Each touch area works on its own, and its light shows the state in one of 8 colours that you choose. The areas stay plain, or you add icons; Optimus sets the colour and the surface design before you order. It runs lights and dimmers, curtains and blinds, scenes, values, the thermostat and logic, with up to 16 functions. It takes its power from the KNX bus.

Black glass
A flat black glass front with no frame. A small light marks each touch area.
8 colours for each area
Each touch area lights in the colour you choose, so each function has a colour of its own.
Each area on its own
Each touch area is a separate button. When two must work together, the installer links them in ETS.
Where it goes
By the door of each room, on the latch side, at 1.2 m to the centre. It mounts flush, with no frame.
