Keyboards with 19.05 mm pitch for data input in informatics, office automation, etc..., enabling to achieve any positioning of the pistons, from a universal body cut out to the desired outer dimensions, without requiring a special tooling for each new model. It comprises a universal body (13) wherein pistons (11) provided with the contact system and the spring are set in place. The position of the pistons may vary as desired every quarter of a pitch on a same line. The keyboard may be fitted with any known contact system. This invention allows to respond immediately owing to its universal character to any need of a user, whatever the importance of the series may be. It associates a monolithic type manufacture, therefore of a high yield-capacity, to an infinity of possibilities.
