Abstract
A keypad apparatus includes a printed circuit () configured for a keypad. Dome actuators () are placed on top of the printed circuit. A backlight () with apertures () is placed over the dome actuators such that the dome actuators rest entirely within their associated apertures. This assembly is covered with a retainer () placed on top of the backlight to form a flat-profile keypad that can be used on an exterior of a phone housing (). The retainer can be labeled to define the key functions, or a preferred replaceable key label () can be placed over the retainer. This provides an integral assembly with key labels that are easily customized.
