摘要： A key top includes a body part having a first width and a flange formed on a lower end portion of the body part so as to have a second width which is larger than the first width. A click rubber is provided on a bottom face of the body part of the key top. The click rubber is elastically deformable such that the key top is vertically moved between an upper first position and a lower second position. A case is formed with a first chamber and a second chamber. The first chamber has a third width which is larger than the first width but smaller than the second width, for accommodating the body part of the key top therein. The second chamber is continued from the first chamber and has a fourth width which is larger than the second width, for accommodating the flange of the key top and the click rubber therein.

摘要翻译： 键顶包括具有第一宽度的主体部分和形成在主体部分的下端部分上的凸缘，以具有大于第一宽度的第二宽度。 在键顶的主体部分的底面上设有点胶。 点击橡胶可弹性变形，使得键顶在上第一位置和下第二位置之间垂直移动。 壳体形成有第一室和第二室。 第一室具有大于第一宽度但小于第二宽度的第三宽度，用于将键顶的主体部分容纳在其中。 第二室从第一室继续，并且具有大于第二宽度的第四宽度，用于容纳键顶的凸缘和止回橡胶。
