ABSTRACT:
In order to be able to produce smaller units whenever needed from a keyboard that consists of an integral multiple key-guiding arrangement (3), a gummous mat (4) with resetting domes for keys (1) and a contact level (8), structural features are disclosed which particularly simplify a division of the multiple key-guiding arrangement (3). The structural features are such that the multiple key-guiding arrangement is divided into segments and the segments are interconnected with one another by connecting bars (17), and the connecting bars (17) can be divided by means of tools.
