  • Patent number: 8923935
    Abstract: A mobile terminal including a wireless communication unit configured to wirelessly communicate with at least one other terminal; a display unit configured to display information; a circuit board having one surface with a plurality of switches thereon; and a keypad disposed over the circuit board and having keys that when pressed, contact corresponding switches on the circuit board. Further, the keypad further includes a plurality of actuators corresponding to and protruding towards the plurality of switches; key-shaped parts laminated on the actuators, respectively, and each having a predetermined height; and a film part disposed to obscure the key-shaped parts and having one surface with key marks in correspondence with the key-shaped parts so as to form the keys of the keypad. In addition, the key-shaped parts and the film part are integrally formed together.
