摘要： A contact keyboard comprising a plurality of keys (10) each having an actuator (11) movable axially in opposition to the action of an elastic element (22) to effect the connection of parts (23-25) of an electric circuit. The actuators (11) are slidable in guide recesses (12) formed by moulding in a single block (15) of plastics material. Assembly of the actuators, the guide block, the elastic elements and the electric circuit on a supporting plate (16) can be effected automatically. Assembly takes place with the block (15) upside down, on the plate (16). The actuators (12) are moulded in one piece with connecting sprues and are inserted in one operation. The sprues are then removed, the elastic elements (22) are put in place and then a printed circuit board (26) is fitted.
