Keyboard and keyswitch

A keyboard, comprising:

• a base, having a circuit board;
• a first keycap, disposed above the base, the first keycap having a first horizontal keycap surface and a keycap skirt, the keycap skirt bending and extending from the first horizontal keycap surface toward the base;
• a first lift mechanism, disposed between the base and the first keycap, the first keycap being up and down movable relative to the base through the first lift mechanism;
• a first touch circuitry portion, disposed on the first horizontal keycap surface;
• a connection circuitry portion, extending outward from the first touch circuitry portion and connecting the first touch circuitry portion and the circuit board, the connection circuitry portion extending downward and over a lower edge of an external surface of the keycap skirt;
• a second keycap, disposed above the base, the second keycap having a second horizontal keycap surface;
• a second lift mechanism, disposed between the base and the second keycap, the second keycap being up and down movable relative to the base through the second lift mechanism;
• a second touch circuitry portion, disposed on the second horizontal keycap surface;
• and
• an outer covering layer, covering the first touch circuitry portion, the second touch circuitry portion, and at least one portion of the connection circuitry portion simultaneously;
• wherein the circuit board has a substrate, and the substrate extends to form the first touch circuitry portion and the connection circuitry portion.
