Abstract
A touch control keyboard includes a plurality of keycaps, a plurality of touch key parts, a plurality pairs of conductive distributions, a first circuit board, and a second circuit board. An upper part of each keycap includes a touch key part having a coupling capacitor. The touch key parts and the pair of conductive distributions and the first circuit board are electrically connected. The first circuit board detects the coupling capacitors of the touch key parts by using the pair of conductive distributions to generate a first key signal. The second circuit board detects keystrokes of the keycaps to generate a second key signal.
