Abstract: A deflection web is provided for use in a keypad assembly. The deflection web comprises a plurality of actuators resiliently coupled together by a flexible membrane. Each actuator of the deflection web corresponds to a key of the keypad assembly, and for each actuator, the flexible membrane comprises a corresponding radially outwardly extending flange whose thickness varies in a direction from the corresponding actuator. In some instances, the thickness of the flange may increase as the flange extends a distance radially outward from its corresponding actuator. A method for creating the deflection web of the keypad assembly and a method for assembling the keypad assembly are also provided.

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.
