Abstract: A keypad assembly comprises a keypad (1), a rubber plate (3), and an intermediate plate (2) interposed between the keypad and the rubber plate. The intermediate plate includes a base sheet (20), and a plurality of apertures (22) defined in the base sheet. Each aperture has a shape corresponding to a periphery of a leg portion (12) of a corresponding key (10) of the keypad. When pressure is applied on a key, the key travels downwardly and contacts the rubber plate through the corresponding aperture of the intermediate plate, and the rubber plate transmits the pressure to a switch assembly. When the pressure on the key is released, resilient force of the rubber plate causes the rubber plate and the key to return to their original positions.
