Abstract: An elastic and tactually-activated structure is applicable to keyboard and comprises a dome-shaped elastic member having a plurality of vent holes arranged on the bottom side thereof and separated with a predetermined distance. The inventive structure further comprises a hard film having an opening corresponding to the location of key of the keyboard, and the bottom end of the elastic member which has a larger diameter being attached upon the opening. The elastic and tactually-activated structure is placed upon the conductive film of the key and the cap of the key is placed upon the top end of the elastic member which has a smaller diameter. When the cap is suppressed, the elastic member is compressed accordingly such that the bump of the elastic member will pass through the opening of the hard film and touch the contact and circuit on the conductive film. The key is therefore formed a closed circuit. In the present invention, the elastic member is directly attached on the hard film, thus simplifying the assembling process and preventing the random bounce of the elastic and tactually-activated structure.

Abstract translation: 弹性和触发式结构适用于键盘，包括一个圆顶形的弹性件，其具有布置在其底侧上并以预定距离分开的多个通气孔。 本发明的结构还包括具有与键盘的键的位置相对应的开口的硬膜，并且具有较大直径的弹性构件的底端附着在开口上。 弹性和触觉激活的结构被放置在键的导电膜上，并且钥匙的盖被放置在具有较小直径的弹性构件的顶端上。 当盖被抑制时，弹性构件被相应地压缩，使得弹性构件的凸起将穿过硬膜的开口并且触摸导电膜上的触点和电路。 因此，钥匙形成闭路。 在本发明中，弹性构件直接安装在硬膜上，因此简化组装过程并防止弹性和触觉结构的随机反弹。

Abstract: A key switch assembly for use in a keyboard employing pressure sensitive electric switches disposed within a keyboard housing is provided. The key switch assembly includes a key switch socket member integrally formed on an upper panel of the keyboard housing to project axially upward therefrom. The key switch socket member includes an inner wall portion defining a receiving bore which has formed thereon an axially extended guiding slot spaced from a pair of appropriately spaced and radially protruding guiding projections which are provided with upwardly exposed beveled surfaces. The key switch assembly also includes a key top member displaceably coupled to the key switch socket member which is formed with an axially extended key stem. The key stem is coaxially received through the receiving bore of the key switch socket member and includes an outer surface portion on which are formed a pair of axially extended guiding rails slidably engaged respectively by the guiding projections of the key switch socket member and a radially protruding guiding rib which slidably engages the guiding slot of the key switch socket member. A pair of resilient projections are provided on the key stem to resiliently engage respectively the guiding projections of the key switch socket member.

Abstract: A scissors-type key switch comprising a key top, a scissors-type supporting bracket, a base member, an elastic actuator, a membrane switch, and a bottom plate is provided. The membrane switch, the elastic actuator, and the base are disposed above the bottom plate. The scissors-type supporting brackets are pivotally supported and received on the base by the pivotally engagement between the pin shaft of the supporting brackets and the connecting holes of the base. The key top is also pivotally connected to the scissors-type supporting brackets by the connecting slots of the key top and the pin shafts of the supporting bracket. This scissors-type key switch features a simplified structure resulted from reduced number of components and durable operation wherein the key top can readily move down and up without rolling thereof. The manufacturing cost is advantageously reduced while the throughput is considerably increased.
