Disclosed is a keypad assembly including a keypad; a touch sensor having a light-guiding plate, the touch sensor being positioned beneath the keypad so as to reflect light incident on the light-guiding plate towards the keypad; and a switch member positioned beneath the touch sensor. The keypad assembly can provide rear lighting without increasing the thickness. 2 The user can easily recognize whether or not key buttons are pressed correctly and select electric contacts from the touch sensor or the switch member as desired.
