Abstract

A keyboard includes a plurality of keyswitches, a plastic baseplate, and a membrane circuit board. Each keyswitch has a keycap, a lifting mechanism and an elastic member. The lifting mechanism is movably connected to the keycap. The elastic member abuts against the keycap. The plastic baseplate has a first hole formed corresponding to each elastic member and has a connecting structure corresponding to each lifting mechanism. The connecting structure is movably connected to the lifting mechanism to make the keycap movable relative to the plastic baseplate. The membrane circuit board is disposed under the plastic baseplate. Each elastic member passes through the first hole on the plastic baseplate to be disposed on the membrane circuit board. When the keycap is pressed, the elastic member deforms downward to trigger the membrane circuit board. When the keycap is released, the elastic member returns the keycap to its original position.
