Abstract
Relatively moveable portions of a flexible printed circuit member are interconnected by a web that extends between the moveable portions and is disposed in a cavity within a hinge interconnecting separately moveable parts of a split keypad assembly. The web portion of the flexible printed circuit is folded so that it is coaxially aligned with the axis of rotation of the moveable portions of the keypad assembly. The design and arrangement of the flexible printed circuit member avoids bending the flexible printed circuit member about an axis perpendicular to the member when the keypad assembly is opened or closed, and provides a vertically assemblable structure that completely encloses the interconnecting web portion of the printed circuit member, thereby avoiding the need for external connectors between the moveable elements of the keypad assembly.
