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.
Claims (9)
1. A printed circuit board for a keyboard assembly for use in a mobile device, the keyboard assembly having a plurality of keys in a key layout, the printed circuit board comprising:
a plurality of contacts arranged in a contact layout for actuation by different combinations of keys in different key layouts, at least two of the plurality of contacts underlying each of at least one key of the plurality of keys in one of the different key layouts, the at least one key for actuating only one of the at least two of the plurality of contacts.
a plurality of contacts arranged in a contact layout for actuation by different combinations of keys in different key layouts, at least two of the plurality of contacts underlying each of at least one key of the plurality of keys in one of the different key layouts, the at least one key for actuating only one of the at least two of the plurality of contacts.
2. The printed circuit board of claim 1 wherein the contact layout is arranged to correspond with key positions in the different key layouts.
3. The printed circuit board of claim 1 wherein the contacts are arranged in rows.
4. The printed circuit board of claim 1 wherein the contacts are arranged in columns.
5. The printed circuit board of claim 1 wherein at least some of the contacts are dome switches.
6. The printed circuit board of claim 1 wherein at least some of the contacts are printed on the printed circuit board.
7. The printed circuit board of claim 1 wherein the plurality of keys are arranged in a QWERTY keyboard layout.
8. The printed circuit board of claim 1 wherein the plurality of keys are arranged in a telephone keypad layout.
9. The printed circuit board of claim 1 wherein the plurality of keys are arranged in a key layout selected from the group consisting of: QWERTZ, AZERTY, Dvorak, and alphabetic.
