ABSTRACT:
A mobile station for receiving and generating wireless communications signals. The mobile station includes layers of translucent materials each having a visual characteristic and overlapping portions that define another visual characteristic. The layers can be used to define keys overlying pressure sensitive regions of a wireless communications signal processing assembly (e.g., dome contacts on a printed wiring board). Keys constructed of two layers have a first and second visual characteristics defined individually by the first and second layers, respectively, and a composite visual characteristic defined by the overlapping portions of the layers. For instance, the first and second visual characteristics may be two different colors that in the overlapping region form a composite color that is aesthetically attractive and distinguishes that portion of the key for easy identification during use. Each of the keys may also include a channel defined between pairs of the plungers to prevent cross-talk between the plungers.
