description The utility model relates to a photosensitive press key which comprises a press key body and a photosensitive color layer, wherein the photosensitive color layer is arranged at the bottom end of the press key body and a plurality of words and patterns are formed on the photosensitive color layer. The photosensitive color layer absorbs light energy, the first change in color is generated. Through the other kind of light irradiation, the second change in color or more than two kinds of change in color are generated. Therefore, a visual effect with dual display is generated. The utility model solves the disadvantages that the existing press key only has a fixed color, or the change in color of the existing press key is single through the characteristic of the photosensitive color layer which absorbs light energy. Therefore, a beautiful effect that the appearance of the press key has various kinds of change in color and the kinds of change in color are overlapped is increased. In addition, a color changing region is adjusted and words or patterns generated by the second color are obviously displayed.
