Abstract (en)
[origin: EP1137027A2] A key panel (410) comprises a key pad (413) having a number of key sites (425) provided thereon that define an aspect ratio for the key pad (413). A strip of printed wiring material (421) is positioned adjacent the key pad (413). A number of switch contact sites (424) provided on the strip of printed wiring material (412) define an aspect ratio for the strip of printed wiring material (412) that is greater than the aspect ratio of the key pad (413). The strip of printed wiring material (412) is provided with at least one fold (430) therein so that each of the number of switch contact sites (424) provided on the strip of printed wiring material (412) is generally aligned with a corresponding one of the number of key sites (425) provided on the key pad (413). <IMAGE>
