<p>The device is designated to display either one of two contrasting signals. The device comprises a number of plates (12) which are positioned essentially in parallel and in a slightly inclined position whereby gaps are formed between the plates. Flanges (18) are arranged to be displaced between a first position in which they are covered by the plates (12) and a second position in which the flanges (18) will be positioned in front of the plates (12). In this manner the indicating device in accordance with the invention may be made to display two different signals in that the flanges (18) and the plates (12) have colours of contrasting nature. The invention likewise concerns the use of the indicating device in which the latter forms part of a module unit used to form figures.</p> |
