Reconfigurable user interface device

A user-interface device comprises a plurality of indication elements (3), each provided with a visual indication (4), mounted on a structure (5). The indication elements (3) comprise identification means (9b, 10, 11, 11') adapted for co-operating with detection means (6, 7) of the device (1), for unique identification the indication elements (3). The identification means (9b, 10, 11, 11') comprise an electrically conductive layer (10) on a respective side face (6b) of the indication element (3) and an electrically insulating layer (9b) superimposed on the electrically conductive layer. The detection means (6, 7) comprise one or more contact elements (7) set up against a respective a side face (6b) of the indication element (3). The electrically insulating layer (9b) has one or more windows (11) for exposure of respective local portions of the underlying electrically conductive layer (10), each window (11) being made in a position substantially corresponding to a respective contact element (7).
