Abstract (en)
[origin: EP2568489A1] The device (10) has a status indicator device including a light guide (16) and two LEDs (14). The LEDs are controlled independently by a control device (12) such that the light of different colors is passed through the same light guide. The mixed colors are generated in addition to the individual colors of LEDs, for displaying four states. An independent claim is included for a method for providing the status indication device in the protective switching device.
