摘要： A narrow key switch for a low travel keyboard and methods of fabrication are described. The low-travel keyboard having narrow keys is suitable for a thin-profile computing device, such as a laptop computer, netbook computer, desktop computer, etc. The keyboard includes a key cap positioned over an elastomeric dome and a two-part scissor mechanism having two separate linkage structures on opposite sides of the dome. A link bar is also provided to transfer a load from a side of a key to the center if the key cap is depressed in an off-center manner. Transferring the load to the center helps to deform the elastomeric dome so that it can activate the switch circuitry of the membrane on printed circuit board underneath the dome. Separating the linkage structures into two separate parts allows for the use of a full-sized elastomeric dome for a narrow key switch. The full-sized dome provides the desired tactile feedback to a user. Thus, the tactile feel of the key is not compromised even thought the key is narrower than a conventional key.
