Embodiment

Below in conjunction with accompanying drawing, to this novel above-mentionedly is described in more detail with other technical characterictic and advantage.

One, first embodiment:

See also Fig. 1, shown in Figure 2, the place is provided with a guide pillar 11 in button 1 bottom surface, and described guide pillar 11 can be square column type or cylindrical, and described guide pillar 11 side face appropriate locations vertically are provided with several guide grooves 111; One framework 2, corresponding guide groove 111 positions at described guide pillar 11 of its inner rim are established a guide rail 22 respectively, install a shell fragment 3 in shell fragment groove 21, substrate 31 upper ends link the downward elastic arm 32 of a turnover and are a gradient, described elastic arm 32 is established a hook 33, when making the guide pillar 11 of button 1 embed in the frameworks 2, the guide groove 111 on the described guide pillar 11 just can embed the guide rail 22 of framework 2, and the hook 33 of then described shell fragment 3 is fastened on the pressure section 113 of described button 1 bottom surface; One elastomer 4 is put below framework 2, and held by the guide pillar 11 of button 1, and a thin film switch 5 is put below framework 2 and elastomer 4.
