1. A keypad apparatus comprising:
a dome-switch assembly having:
a housing;a dome; anda dome sheet carrier to couple the dome to the housing; a plastic carrier having at least a first surface, a second surface adjacent the first surface, a third surface adjacent the second surface, and a plurality of flexible arms, the dome-switch assembly being coupled to the first surface; a conductive pattern printed on at least the first and second surfaces of the plastic carrier, the dome to engage a first portion of the conductive pattern formed on the first surface of the plastic carrier when the dome-switch is coupled to the plastic carrier, a second portion of the conductive pattern being printed on the plurality of flexible arms; and a circuit board having a main surface to be positioned substantially parallel relative to a display of an electronic device and a side surface of the circuit board substantially perpendicular relative to the main surface of the circuit board, the circuit board including one or more plated slots being exposed via the side surface, the second portion of the conductive pattern of the flexible arms to engage the plated slots to electrically couple the circuit board to the first portion of the conductive pattern. |
