| In a keyboard arrangement and method for identifying a pressed key according to the present invention, conductor lines (4', 6') at each key (B), which may be connected together, are connected to a ground plane (24, 23, 27) as a response to a pressing (P) of a key. The pressed key (B) is identified by detecting the conductor lines that are connected to the ground plane. All the conductor lines may be connected as pulled-up inputs of a detector circuit, and any conductor line or combination of conductor lines may be used to identify a key. A noticeably greater number of keys may be simply identified with the same number of conductor lines than is possible in a solution according to the prior art. In an advantageous embodiment of the present invention, the means for connecting the conductor lines (4', 5', 6', 7') to the ground plane (27) is a conductive plate (23), which essentially covers the whole keyboard. This also provides a good shield against electrostatic discharges and other interference. | ||||||

| An improved planar contact array switch having reduced susceptibility to electrostatic discharge includes a printed circuit board which carries at least one switch contact foil pair. Sandwiched between the circuit board and an insulative overlay is a dome-shaped disc which, when depressed, completes an electrical circuit between the switch contact foil pair. Bordering the periphery of the printed circuit board so as to bound the area occupied by each of the switch contact foil pair is a ground foil which advantageously is provided with at least one inwardly extending charge conductive foil which runs adjacent to each of the switch contact foil pairs for conducting any electrostatic discharge which penetrates the overlay within the area bordered by the ground foil. To facilitate the conduction of electrostatic discharges to the perimeter ground foil through the charge conductive foil, a spark gap is provided between each of the switch contact foil pairs and the charge conductive foil so that an electrostatic discharge may jump the spark gap and be conducted via the charge conductive foil on the ground plane to circuit ground. | ||||||

| The invention relates to a keyboard structure (13) which is particularly suited to film keyboards and where EMC protection can be realized by structural means, with fewer auxiliary components than in the prior art. A metal bubble (7), which is the switching member of the keys, is permanently coupled to ground, so that it establishes an ESD protection. The row and column conductors (3a - 4d) are coupled to voltage dividers (11, 12), so that a given row and a given column correspond to a given pair of analog voltage values (V 14, V 16). Each pair of values unambiguously corresponds to a certain key. The analog voltage values are converted to digital form in the A/D converters (19, 20) provided in the microprocessor (8) or in a connected auxiliary circuit, such as a bus buffer. | ||||||
