An illuminated device for setting electric controlled variables comprising a housing 1 and a regulating wheel 6 rotatably mounted therein has, on the front wall 4 of the housing and on the circumferential wall 5 of the regulating wheel, symbols 7,8,9 to identify the controlled variables of the regulating wheel. In the housing 1 there is provided a first light guide 17 which is irradiated by a single light source (22) adjacent a wall 21 and which, via branches 18, 19, conducts the light firstly to the symbols 7, 8 on the front wall 4 of the housing and secondly to the regulating wheel 6. in the regulating wheel 6 there is provided an annular second light guide 34 which receives the light from the corresponding branch 19 of the first light guide 17 and transmits it to the symbols 9 on the circumferential wall of the regulating wheel. <IMAGE> |
