Abstract:
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.
