Keypad keys for handheld mobile communication devices feature flexible key
bodies and actuators extending from the key bodies. Switches below the
actuators are connected in series circuits. All actuators beneath an
intended key must be depressed in order for the circuit to be closed and
the key to be recognized as actuated. The flexible nature of the key
bodies allows one actuator on a given key to be depressed while other
actuators remain non-depressed. This prevents the key from being
recognized as actuated when a only a portion of the key is depressed as
occurs, for example, due to finger overlap.
