The K.1 flat switch line has a consistently straight, regular design. Thanks to the rectangular shape of all insert modules, the optical focus is shifted from the centre of the switch, achieving a greater planar effect. The clearcut, straight geometric lines of the K.1 range meet the wishes of many builder-owners and architects for switch elements that can be integrated into rooms with a timeless character. In addition to the high-grade plastic version in glossy RAL 9010 and RAL 1013, the K.1 line is also available in stainless steel and aluminium.
