    • 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.
    • 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。

    • The present invention provides a contact mechanism which comprises a fixed contact and a movable contact. The fixed contact is formed by arranging two terminals having a plurality of parallel contacts so that the contacts are disposed in an alternating manner and at a predetermined pattern pitch. The movable contact is disposed above the contacts of the fixed contact to be able to connect with the contacts of the fixed contact. The pattern pitch of the contacts is set within a range of 0.4 mm to 0.8 mm. The present invention provides a durable contact mechanism having stable output levels.
    • 本发明提供一种接触机构,其包括固定触点和可动触点。 固定触点通过布置具有多个平行触点的两个端子形成,使得触点以交替的方式和以预定的图案间距设置。 可动触点设置在固定触点的触点上方,以便能够与固定触点的触点连接。 触点的图案间距设定在0.4mm〜0.8mm的范围内。 本发明提供一种具有稳定输出电平的耐用接触机构。
