A keypad assembly includes a pressing surface layer, a pattern layer, an elastic layer, a light guiding layer, and a pressing bottom layer. The pattern layer is under the pressing surface layer. The elastic layer is located between and interlocks the pattern layer and the light guiding layer by adhesive. The pressing bottom layer adheres to the light guiding layer. The keypad assembly has an ideal appearance by lights collection of the light guiding layer. User can feel comfortable when pressing the keypad assembly because of the elastic layer's buffering effect.
