Abstract
A keyboard device includes a circuit substrate, a control unit and plural touch key structures. The control unit is installed on the circuit substrate. Each touch key structure includes a base plate, a keycap, a connecting element and a touch-sensitive circuit layer. The base plate is detachably installed on the circuit substrate. The keycap is located over the base plate. The connecting element is arranged between the base plate and the keycap. The keycap is movable upwardly or downwardly relative to the base plate through the connecting element. The touch-sensitive circuit layer is arranged between the base plate and the keycap, and electrically connected with the control unit. After a touch signal is received by the touch-sensitive circuit layer, the touch signal is transmitted to the control unit, and the touch signal is converted into an input signal by the control unit.
