摘要: A low-profile rubber keypad with good tactile feel and illuminability includes a plurality of layers adhesively bonded to one another. The top layer of the keypad is a silicone rubber overlay having a plurality of keys protruding therefrom. The rubber overlay is adhesively bonded to an actuation layer including a plurality of thin actuating strips. The actuation layer is adhesively bonded to a tactile layer including a plurality of collapsible resilient domes. The tactile layer is adhesively bonded to a shorting layer including a plurality of conductors. The shorting layer is adhesively bonded to a flex circuit layer including a plurality of conductors.
