ABSTRACT:
An keypad comprises at least first and second actuators formed of a substantially translucent elastomeric material. A barrier (103) disposed within the first actuator (200) permits light, emitted by a first light source (105), present inside the first actuator (200) to substantially illuminate at least a portion of the first actuator (200) without substantially illuminating the second actuator (505) and permitting light, emitted by a second light source (503), present outside the first (200) and second (505) actuators, to substantially illuminate at least a portion of the first actuator (200) and at least a portion of the second actuator (505). A method for making a selectively illuminated keypad is also disclosed.
