Specifically, the key cap 30 and the face shell 10 are both formed by injection molding, wherein the material of the key cap 30 may be Polybutylene terephthalate (PBT) and a terpolymer of Acrylonitrile, Butadiene and Styrene (ABS). The panel shell 10 is provided with a keyhole 101, the keycap 30 is accommodated in the keyhole 101, and under the limiting action of the keyhole 101, the keycap 30 can only slide relatively to the panel shell 10 in the axial direction and cannot be separated from the keyhole. When the key cap 30 is a space key, a return key, a shift key, or other keys with irregular shapes or large sizes, a guide structure (not shown) may be disposed on the front shell 10 to guide the movement of the key cap 30, so as to prevent the key cap 30 from tilting when being pressed or lifted. Amortization piece 20 has the effect of buffering the impact force, and in this embodiment, the material of amortization piece 20 is silica gel, and in other embodiments, amortization piece 20 also can be the material of accessible turn into the internal energy of self with the impact force such as spring, bullet piece and sponge.

It can be understood that when the force of striking the key cap 30 by the user is large, the noise damping member 20 can absorb a part of the impact force to reduce the force of collision of the key cap 30 with the panel case 10, thereby reducing noise. When the force of the user striking the key cap 30 is small, the noise damping member 20 can absorb the whole impact force, so that the key cap 30 cannot contact the panel 10, or the key cap 30 contacts the panel 10 in time without collision between the two.
