ABSTRACT:
The invention concerns a touch-sensitive surface (15) electrical control device comprising at least two adjacent active zones (3, 5, 7) for controlling in each active zone (3, 5, 7) a specific electrical function and a coating (13) provided on the touch-sensitive surface (15) and having surface ribs (9) for delimiting said active control zones (3, 5, 7). The invention is characterized in that the lower surface (18) of a rib (9) separating two adjacent active zones is shaped like a tensioned vault (20) between posts (17) which are solely supported outside the active zones of the touch-sensitive surface (15).
