Abstract:
1. A mobile terminal comprising: a terminal body; a circuit board located in the terminal body, the circuit board including a plurality of switches located thereon; and an input device located at the terminal body, the input device being configured to input a control command, the input device including: a key top configured to be pressable in one direction, the key top having a rear surface facing the circuit board; a plurality of pressing portions protruding from the rear surface of the key top, each pressing portion being configured to extend toward a corresponding switch of the plurality of switches; and at least one dummy pressing portion disposed between one pressing portion and another pressing portion of the plurality of pressing portions, the at least one dummy pressing portion being supported by the circuit board when the key top is pressed such that, when one switch of the plurality of switches is pressed by said one pressing portion, the at least one dummy pressing portion is configured to prevent said another pressing portion from pressing another switch of the plurality of switches, wherein the plurality of pressing portions includes first and second actuators spaced from each other, wherein the plurality of switches include first and second switches located on a first surface of the printed circuit board facing the first and second actuators, the first and second switches corresponding to the first and second actuators, respectively, and a third switch located on a second surface of the printed circuit board facing away from the first surface, wherein the terminal body includes a supporting member spaced from the circuit board, wherein the at least one dummy pressing portion includes a first dummy actuator disposed between the first and third switches and a second dummy actuator disposed between the second and third switches, and wherein the third switch is configured to be pressed by the supporting member when the circuit board moves toward the supporting member by displacement of the first and second dummy actuators.
