Abstract (en)
[origin: EP0101208A2] A keyboard sub-assembly for a typewriter has a base-board (1) formed with a plurality of upstanding projections (3) which receive keys (4) with a snap action. Each key (4) is a push-fit onto the corresponding projection (3), and each key (4) is retained on the baseboard (1) by means of a lug (15) having a lip (17) which snap-engages within a recess (12) on the underside of the baseboard (1). A coil compression spring (18) is interposed between each key (4) and the corresponding projection (3). The sub-assembly of the baseboard (1) and the keys (4) can be assembled into a deck (29) with a push-fit, as a result of the baseboard having projecting lugs (27) which snap-engage within slots (32) formed in the deck (29). The keys (4) shroud the projections (3) so as to prevent foreign matter reaching the underside of the baseboard (1).
