ABSTRACT:
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.
