Abstract
A backlit key assembly having a reduced thickness for an electronic device, and an electronic device having such a backlit key assembly are provided. The key assembly utilizes a local sink (recess) in a backing plate of the key assembly to lower the light source (e.g. LED) and flexible printed circuit board relative to the backing plate. The key assembly described herein provides a suitable leading space for the light source while permitting the overall thickness of the key assembly to be reduced compared with conventional backlit key designs.
