| A keypad device for a mobile telephone or other device utilizing a keypad or keyboard is comprised of a flexible substrate and a keypad cover. The flexible substrate includes a plurality of keys affixed to the surface as well as a plurality first conductive strips associated with each key. The keypad cover is attached to the flexible substrate. The keypad cover typically includes holes that permit the plurality of keys to protrude through the keypad cover. In addition, the keypad cover further includes a plurality of second conductive strips that selectively contact a corresponding first conductive strip on the flexible substrate. The plurality of first conductive strips is coupled to ground and the plurality of second conductive strips is coupled to logic circuitry. Or, in another embodiment, both sets of conductive strips are coupled with the logic circuitry. The default position of the keypad device has each of the first conductive strips in contact with each of the corresponding second conductive strips. This creates a short circuit condition that prevents key signals from being received by the logic circuitry. When a particular key is depressed to the point where the first conductive strip associated with that particular key is separated from the second conductive strip corresponding to the first conductive strip, the short circuit condition is removed. This allows a signal to be transmitted to and processed by the logic circuitry indicating that a particular key has been selected. | ||||||

| The present invention is a simplified membrane keyboard employing a single flexible sheet. This membrane keyboard is employed in an electronic apparatus having an external case with a nonconducting keyboard surface. This nonconducting keyboard surface has a plurality of depressions corresponding to key switch positions. The keyboard surface is covered by a keyboard sheet. This keyboard sheet has a flexible membrane with opposed first and second surfaces, the first surface disposed adjacent to and substantially covering the keyboard surface of the external case. An interconnection pattern is placed upon the first surface of the flexible membrane. This interconnection pattern has a plurality of conductors and most particularly has a pair of conductors in proximity at each key switch position. Pressure applied to the second surface of the flexible membrane causes the flexible membrane to flex until the two conductors contact a conductive layer disposed in the bottom of the corresponding depression. This contact causes electrical conduction between the two conductors, thereby giving rise to a closed key operation. In a preferred embodiment graphic matter identifying the key areas of the flexible sheet, that is those areas overlying the depressions, is applied to the second surface of the flexible sheet. This invention is adapted for use in calculators, electronic learning aids, electronic games, small computer systems and other electronic apparatuses which employ keyboards. | ||||||

| A computer keyboard employs a single monoblock structure to both support the keys and to define the aesthetic enclosure. The monoblock has multiple key supports into which key bodies are slidably mounted. The keyboard includes a switch membrane disposed on top of the monoblock and a dome sheet positioned on top of the switch membrane beneath the key bodies. The dome sheet has multiple resilient domes with openings formed therein to provide access for the key bodies to corresponding key supports. The domes support the key bodies and provide the "spring-like" feel during operation of the computer keys. The switch membrane has annular switch contacts positioned about the monoblock key supports beneath the domes. As one of the key bodies is depressed, the associated dome buckles and actuates the annular switch contact. The computer keyboard is low cost due to having only one structural component and is quiet due to the position of the rubber or elastomer dome sheet beneath the key bodies. | ||||||
