CA 2476778

A printed circuit board is provided for use in a keyboard assembly of a mobile device having a plurality of keys in a key layout. The printed circuit board has a plurality of contacts, such as dome switches, arranged in a contact layout. The contact layout is such that it can be used with a plurality of different key layouts, each actuating different combinations of contacts. Some keys in a particular key layout are overlying at least two of the plurality of contacts, and such keys actuate only one of the underlying contacts. As such, a common printed circuit board can be used for a plurality of complementary mobile device designs having different key layouts, thereby allowing a manufacturer to realize cost efficiencies.

L'invention concerne une carte imprimée dans un ensemble de clavier d'un dispositif mobile ayant une pluralité de touches selon une disposition de touches. La carte imprimée comporte une pluralité de contacts, tels que des commutateurs de dôme, arrangés selon une disposition de contacts. La dispositin de contacts est caractérisée en ce qu'elle peut être utilisée avec une pluralité de différentes dispositions de touches, chacune desquelles actionnant différentes combinaisons de contacts. Certaines touches dans une disposition de touches particulière surmontent au moins deux des multiples contacts, et de telles touches actionnent seulement un des contacts sous-jacents. € ce titre, une carte imprimée commune peut être utilisée pour une pluralité de modèles de dispositifs mobiles complémentaires ayant différentes dispositions de touches, permettant ainsi aux fabricants de réaliser des économies de coûts.
