Abstract (en)
[origin: EP0278293A2] On an operating console, each operating element is assigned one control field (3) each, which is to be illuminated by an infrared diode, and an event display field (4), which is to be illuminated by a diode to transmit light in the visible spectral range. The activation of the control fields is performed by an attachable coupling pen (5) with a radiation-sensitive reading head. As soon as an activated control field (3) is detected, the light-emitting diode of the associated event display field (4) is connected. The operator thus has the possibility of controlling the operating action he has undertaken. Further processing of the operating action can be made to depend on the activation of separate release switching means. <IMAGE>
