Abstract
A keyswitch structure includes a keycap layer having a keycap region, a circuit layer disposed under the keycap layer, at least a haptic actuator disposed under the circuit layer and electrically connected to the circuit layer, a cushion layer disposed under the circuit layer and having an accommodation space for accommodating the haptic actuator, a sensing unit disposed under the cushion layer, and a control circuit coupling the sensing unit and the circuit layer, wherein when an external force is applied and delivered through the cushion layer to trigger the sensing unit, the sensing unit outputs a trigger signal, and the control circuit receives the trigger signal and outputs a driving signal to drive the haptic actuator to vibrate.
