Abstract (en)
[origin: DE19505852C1] A keyboard has an integrated film (6) that provides protection against moisture and contaminating particles. The keyboard is of a contact membrane type (2) that is formed with dome shaped projection is that are engaged by stems (5) from the keys (9) that move vertically to deform the domes to establish contact. The displacement range of the keys is limited by a rigid frame (3) and the foil lies against the frame and is fixed around the edge to the front panel of the housing. The foil is embedded into the keys.
