Abstract
A mobile terminal includes a signal input module for inputting a signal as an opening formed at a case of a terminal body is pressed, and the signal input module includes an input key, a light guiding unit, a key mold, a light emitting unit, a circuit board, a dome switch and an actuator, which are all integrally fixed together and moved by being pressed. The light emitting unit is accommodated in a key mold having an opening for allowing light to be transferred to the light guiding unit. The input key, the light guiding unit, the key mold and the light emitting unit are mounted onto one surface of the circuit board, the circuit board is moved by being pressed, and the dome switch mounted onto another surface of the circuit board is transformed so as to generate a signal.
