The invention concerns a connecting device which is intended to replace a keypad of a hand-held electronic device, such as e.g. a mobile telephone or a remote control device. A connecting disc (1) forming part of the device is tiltable about its center in different directions from a neutral position in order to bring electrical contact means (6, 10, 11) together for the purpose of generating electrical information signals. On one of its sides the connecting disc (1) is provided with alternating crests (4) and dales (5) departing radially from the center of the disc (1). A contact field (6) is provided on each crest (4). A printed circuit card (7) cooperating with the connecting disc (1) is formed with alternating crests (8) and dales (9). Each dale (9) is in this case provided with at least one pair of contacts (10, 11). The connecting disc (1) is arranged, by being tilted in any direction, to slide by means of a crest (4) into a dale (9) in the circuit card (7) to close the circuit between the contact field (6) on said crest (4) and the pair of contacts (10, 11) on said dale (9). |
