Abstract
A sequential control device, especially for a scrolling menu, comprises a key (8) mounted movably on a support (2) and able to actuate at least one contactor (16, 18) in response to an external action exerted in a given direction. The key (8) includes an arm (12) having a longitudinal direction, by way of which the contactor (18) is actuated in a direction substantially perpendicular to the longitudinal direction of the arm (12). The longitudinal direction of the arm (12) is substantially parallel to the direction of the external action exerted on the key (8), and the contactor (18) is mounted on a printed-circuit card (14) substantially parallel to the longitudinal direction of the arm (12).
