    • A keyboard mechanism for a low-travel keyboard and methods of fabrication are described. The low-travel keyboard is suitable for a thin-profile computing device, such as a laptop computer, netbook computer, desktop computer, etc. The keyboard includes a key cap that can be formed of a variety of materials in the form of a flat slab. The key cap is attached to one end of a support lever that supports it from underneath. In one embodiment, the support lever is formed of a rigid material and is pivotally coupled with a substrate on the other end. In another embodiment, the support lever is formed of a flexible material and is fixedly attached to the substrate on the other end. The portion of the support lever that is attached to the key cap is positioned over a metal dome that can be deformed to activate the switch circuitry of the membrane on printed circuit board underneath the dome.
    • 描述了用于低行程键盘的键盘机构和制造方法。 低旅行键盘适用于诸如膝上型计算机,上网本电脑,台式计算机等薄型计算设备。键盘包括可由平面形式的各种材料形成的键帽 平板 钥匙盖连接在支撑杆的一端,支撑杆从下面支撑。 在一个实施例中,支撑杆由刚性材料形成并且在另一端上与基底枢转地联接。 在另一个实施例中,支撑杆由柔性材料形成,并且在另一端固定地连接到基板。 附接到钥匙盖的支撑杆的部分位于可以变形的金属圆顶上,以激活位于圆顶下面的印刷电路板上的膜的开关电路。
