Title: Key assembly for electronic machines

Abstract: A key assembly has a circuit board, an elongated flexible key, and an elastically deformable support. The flexible key has a center and two side portions. The side portions and the elastically deformable support each have electrically conductive regions that are positioned over electrical contacts of the circuit board. A sufficient downward force on the flexible key causes one of the electrically conductive regions to contact the underlying electrical contacts. With this configuration, the key assembly provides an electrical output signal even if the human operator applies the downward force on a side portion instead of on the center portion of the flexible key shell.
