Abstract

The device has a number of selection levers (6) rotating about a corresponding number of parallel pivots (7), and a number of piezoelectric actuators (18) connected to the levers (6) and fitted to corresponding bases (23). The levers (6) and actuators (18) are housed in a casing (31) defined by a frame (13) for supporting the levers (6) and by two walls (26, 28) for supporting the actuators (18). The device is provided with adjusting means (64) for adjusting the relative position between the actuators (18) and the selection levers (6); and each actuator (18) carries a group of three rigid pins (38, 40, 41) which fit inside corresponding bushes (48) located on a printed-circuit board (47) and connected electrically to a number of other pins (46) of a multiple connector (35) in turn connected to the casing (31).
