Touch control keyboard

A touch control keyboard, comprising:

• a supporting plate;
• a plurality of keycaps, wherein each keycap comprises a keycap column, a cap, and a touch key part, the keycap column is fixed to the cap, and the touch key part is disposed at a contact surface of the cap opposite to another side of the keycap column and has a coupling capacitor;
• a plurality of supporting housings, wherein each supporting housing comprises a fixed end and an open end opposite to each other, and the fixed end is fixed to the supporting plate, wherein the keycap columns of the keycaps are respectively combined to the supporting housings;
• a plurality pairs of conductive distributions, wherein each pair of conductive distribution is correspondingly disposed on the keycap and the supporting housing connected to each other and is electrically connected to a touch key part of the keycap;
• a first circuit board, comprising a plurality pairs of conductive wires, wherein each pair of conductive wires is respectively disposed corresponding to the keycap, and each pair of conductive wires is electrically connected to the touch key part by means of the pair of conductive distributions, to detect the coupling capacitor to generate a first key signal;
• and
• a second circuit board, comprising a plurality of key contact points and a plurality of elastic components configured respectively corresponding to the key contact points, wherein each elastic component receives squeezing of the corresponding keycap column, so that the corresponding key contact point is stressed and changes from a normally open state to a conductive state to generate a second key signal.
