A keyboard comprises a substrate upon which the individual key contacts and associated interconnection circuitry may be formed using printed circuit tech-niques. The keytop array comprising the individual keytops and electrically conductive bridging contacts may then be assembled to the printed circuit substrate. The depression of a keytop brings the selected bridging contact into electrical engagement with one or more conductive key contacts to close the selected circuit.
