Abstract
A light-pervious bicolor key cap includes: a key frame, having a first color and formed with plural thin ribs, wherein front ends of the plural thin ribs are formed with at least one letter or punctuation in a continuous status without any notch; and a cap cover, having a second color, wherein the letter or punctuation is formed on a surface of the cap cover, an outer side of the cap cover is formed with a material filling protrusion allowing a plastic having the second color to be filled in, and an inner surface thereof is formed with at least one convex piece which is not fixedly combined with the key frame; so that through removing the convex piece having the second color, the letter or punctuation of the cap cover is prevented from being formed with any notch and capable of allowing the light to fully permeate.
