Light-reflecting structures are provided on the lower surface of a cover mounted over the keys of a keypad assembly. The light-reflecting structures reflect light from a vertical-emitting source, such as an LED, to the side surfaces of the individual keys of the keypad assembly. The keypad assembly embodying the present invention provides an efficient and low-cost structure for illuminating the keys of a keypad without the use of lightguides or separate sources of light for each key, thereby also providing a desirable low profile keypad assembly. |
