ABSTRACT:
Adjacent tactile modules (10) together define a row of modifiable Braille cells (11), opposite a row of micro-switches (50), and opposite a row of covers (30). Each of the latter defines a pivoting tab (32) controlling the corresponding micro-switch, a tab connected by an undercut hinge (36) to a fixed part (31) bearing a fixed Braille information display area (40). At the free end of each tab (32), a bent lug (35) forms a stop with the underside of the associated micro-switch (50). On the back of each tab (32), a cylindrical transverse embossing ensures in-line contact with the micro-switch (50). Considered transversely, the series of pivoting tabs (32) exhibits a sinusoidal shape, this enabling a single tab to be actuated selectively with a broad finger. Also, each tab (32) is furnished with a longitudinal guiding rib, for steering the finger.
