Handheld mobile communication device with flexible keys
摘要:
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.
