A touch control device comprises: a button member receiving a touch input; a body member located below the button member; a signal deliverer arranged in the body member for having capacitance changed according to the touch input; a substrate having a receiver which is arranged on the substrate for receiving information about the capacitance from the signal deliverer; and a light emitting member for irradiating light onto the button member.

In some examples, techniques are provided for quick haptic feedback, without the use of a controller, which is local to individual, non-actuating keys, such as keys of a thin keyboard or keypad. The haptic feedback may be in the form of a simulated key-click feedback for an individual key that is pressed by a user such that the finger used to press the key feels the tactile sensation. The haptic feedback mimics the tactile sensation of a mechanical key (e.g., buckling spring, pop-dome key switch) to give a user the perception that they have actuated a mechanically movable key.
