Abstract: A sensing keyswitch including a key body, a key-sensing switch and an enabling switch is provided. The key body includes a key top, and a key driver and an enabler which can move with the key top in the same keystroke cycle. The key-sensing switch electrically connected to a key circuit is in a disabled mode to save power and cannot sense the change of the sensing intensity caused by the movement of the driver. The enabling switch is electrically connected to an enabling circuit, wherein when the enabling switch is triggered by the enabler, the enabling switch outputs an enabling signal through the enabling circuit for enabling the key-sensing switch to enter an enabled mode, so that the key-sensing switch can sense the change of the sensing intensity caused by the movement of the key driver to trigger a key signal.

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.
