Abstract: A touch-sensitive control device is controlled by a control chip to conduct press sensing and/or touch sensing. The touch-sensitive control device includes: a cover; a circuit board disposed at a side of the cover, having a first surface disposed opposite to the cover, and having a second surface facing the cover; a first electrode disposed on the first surface of the circuit board and electrically connected to a control chip; a socket having a conductor; and a spacer disposed between the socket and the first surface of the circuit board, and deformable to change a distance between the first electrode and the conductor, wherein a capacitance change between the first electrode and the conductor of the socket correlates to the distance change between the first electrode and the conductor resulting from a pressing operation onto the cover.
