TOUCH-SENSITIVE CONTROL DEVICE
First Claim
1. A touch-sensitive control device, controlled by a control chip to conduct press sensing and/or touch sensing, comprising:
- 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.
