Illuminated electronic operating unit for building system engineering, has operating elements plugged on bus coupling and uses wall flush mounting technology

摘要

The illuminated electronic operating unit has operating elements plugged onto a bus coupling. and uses wall flush mounting technology The illuminated electronic operating unit (1) has a large area flat light wave conductor (9), acting as a system for the indication of signs, symbols or letters for the operating unit. A light wave conductor (9) receives its light supply across laterally arranged light sources e.g. LEDs (16). Operating elements are directly assigned light sources for indicating their respective condition. The indication of alphanumerical signs is achieved via a light permeable cover (7), which is arranged over the light wave conductor (9).
