Abstract of disclosure A keyboard arrangement wherein key elements (22) are mounted on a printed circuit board (23) requires a good support of said board to withstand the operation forces. This support is achieved by a foamed plastic molded body (27) filling the entire remaining space below a cover (21). The evaluation circuitry (26) is arranged on a separate printed circuit board (25) which is interconnected with the printed circuit board carrying the key elements via a connector (24). This results in a small keyboard arrangement, in a foamed plastic molded body of simple design and in an easy replacement of the evaluation circuitry in case of failure. (Fig. 2)
