    • A keyboard membrane keyswitch assembly comprises a housing (13), a button (11), a compression piston (12) and a rubber element (14). The housing (13) holds the compression piston (12) and the rubber element (14). The compression piston (12) has a cylindrical shape with a vertical guider (121) along its longitudinal axis. The vertical guider (121) is used to connect the assembly to the button (11). A supporting ring (122) is linked to the vertical guider (121) by rib elements (123). The rubber element (14) is adapted to receive the supporting ring (122) of the compression piston (12) thereby maximizing the displacement of the button (11) and preventing the button from tilting when it is depressed.
    • 键盘膜键开关组件包括壳体(13),按钮(11),压缩活塞(12)和橡胶元件(14)。 壳体(13)保持压缩活塞(12)和橡胶元件(14)。 压缩活塞(12)具有沿其纵向轴线的垂直导向器(121)的圆柱形形状。 垂直导向器(121)用于将组件连接到按钮(11)。 支撑环(122)通过肋元件(123)连接到垂直导向器(121)。 橡胶元件(14)适于接收压缩活塞(12)的支撑环(122),从而使按钮(11)的位移最大化并防止按钮在其被按压时倾斜。
