Abstract: A key switch includes a base, a key cap, a first support member and a second support member. The key cap is disposed with respect to the base. The first support member and the second support member are disposed between the key cap and the base. The first support member has a first linkage structure. The second support member has a second linkage structure. The first linkage structure and the second linkage structure abut against each other, such that the first support member and the second support member rotate synchronously with respect to a horizontal axis. When one of the first support member and the second support member horizontally moves with respect to the other one of the first support member and the second support member within a predetermined range along the horizontal axis, the first linkage structure and the second linkage structure keep abutting against each other.

Abstract: A keyboard is disclosed and includes a base plate, a plurality of key structures, a plurality of switches, and a capacitive touch sensing device. Each of the key structures is disposed above the bottom plate and includes a keycap capable of moving up and down relative to the base plate. Each of the switches corresponds to one of the keycaps and is disposed under the corresponding keycap. Each of the keycaps is capable of moving toward the base plate to trigger the corresponding switch. The capacitive touch sensing device is disposed under the key structures, for sensing a touch operation performed on the keycaps. The functionality of the keyboard of the invention therefore improves. The keyboard uses an identical projection area to perform keying and touch operation, which avoids the inconvenience for a user when using both a keyboard and a touchpad in the prior art.

Abstract: A keyboard includes a cover plate having a plurality of first keyholes, an adjustment mechanism disposed under the cover plate, and a plurality of keyswitches. The adjustment mechanism includes an adjustment frame and a plurality of adjustment portions. The adjustment frame includes a plurality of ribs defining a plurality of second keyholes corresponding to the plurality of first keyholes, respectively. Each of the adjustment portions is proximate to a corresponding one of the second keyholes. Each of the keyswitches includes a tactile feedback member and is located in corresponding first and second keyholes, so that the adjustment portion corresponds to the tactile feedback member of its corresponding keyswitch. The adjustment frame is movable relative to the cover plate, so that each of the adjustment portions drives a portion of the tactile feedback member to move, to change tactile feedback of the keyswitches.

Abstract: A keyboard includes a base and a plurality of keyswitches. The keyswitches are disposed on the base. One of the keyswitches includes a key cap, a first support member and a second support member. The first support member is Z-shaped and has a first sliding portion and a first rotating portion, wherein the first sliding portion is selectively disposed on one of the base and the key cap and the first rotating portion is selectively disposed on the other one of the base and the key cap. The second support member is Z-shaped and has a second sliding portion and a second rotating portion, wherein the second sliding portion is selectively disposed on one of the base and the key cap and the second rotating portion is selectively disposed on the other one of the base and the key cap.
