Abstract
A thin keyboard device is described herein. In one or more implementations, a keyboard device includes a plurality of keys, and a housing that includes a structural printed circuit board (PCB). The structural PCB includes, for each of the plurality of keys, a first conductive trace and a second conductive trace. The keyboard device further includes a key-switch mechanism for each of the plurality of keys. The key-switch mechanism includes a conductive material oriented towards the first conductive trace and the second conductive trace, and is configured to cause the conductive material to move downwards, when the key is depressed, to electrically connect the first conductive trace and the second conductive trace of the depressed key.
