Cala KNX IL (CO2): New colour variant in deep black

News of 09 July 2026

Tried-and-tested KNX functions. New colour option.

When selecting switch components, it is not only the functionality that matters, but also the appearance. With the new Deep Black (RAL 9005) colour variant, Cala KNX IL and Cala KNX IL CO2 can now be seamlessly integrated into projects with dark switch ranges.

Cala KNX IL visualises status messages and warnings using a coloured LED indicator. Cala KNX IL CO2 extends these functions with an integrated CO2 sensor and automatic ventilation control. Both variants integrate seamlessly into standard 55 mm switch ranges or Swiss 60 mm installation systems, offering a wide range of options for visualising KNX system conditions.

Whether room occupancy, window status, air quality or technical status messages, Cala KNX IL and Cala KNX IL CO2 provide intuitive visualisation directly in the room. The new colour variant also offers additional design flexibility for high-quality KNX projects.
