In the preferred design, the design has two forms. The first one corresponds to the unit assembly 101, which uses a combination mode of three black keypads 221 and four white keypads 222 (see Figures 3-4) to form seven keys. The second type of corresponding unit assembly 102 uses a combination mode of two black keypads 221 and three white keypads 222 (see FIG. 5) to form five keys.
