摘要： An arrangement of a plurality of status keys in a keyboard for entering information in an electronic device. The keyboard comprises a plurality of regular keys (32,34,36) connected to a resistive strip (20) at a plurality of locations for providing a first signal when one of the regular keys is pressed and the first signal is indicative of the location associated with the pressed regular key; a plurality of resistors (22-28), each having a different resistance, connected in series to the resistive strip, and separately connected in parallel to the status keys (42-48) so that the resistors can be selectively by-passed by pressing one or more status keys, wherein a second signal is provided when one of the regular keys is pressed together with at least one status key, and wherein the second signal is indicative of the resistance the status key for identifying the pressed status key.

摘要： A keypad for a portable electronic device comprises a number of pressable keys (402). Associated with each key, there are switching means (501, 502, 611, 612, 620, 621, 622, 801, 1106) for realizing a switching function as a response to the key being pressed. Additionally there are illumination means (503, 601, 610, 623, 704, 803, 1201, 1302) for illuminating at least a part of the keypad. The illumination means (503, 601, 610, 623, 704, 803, 1201, 1302) comprise light sources (503, 601, 610, 623, 704, 803, 1201) such as semiconductor light-emitting devices made of layered foil structures. At least one of said light sources (503, 601, 610, 623, 704, 803, 1201) is located in the immediate vicinity of the switching means (501, 502, 611, 612, 620, 621, 622, 801, 1106) associated with at least one key.
