Key switch device with low-profile key top which gives three-dimensional appearance and looks thicker than actual one

摘要

A key switch device having a key top colored in a dark shade on the right and front side surfaces, in a light shade on the top surface, and in an intermediate shade between the color of the right and front side surfaces and the color of the top surface, on the left and rear side surfaces. Because of these different color shades, the right and front side surfaces look as if shaded; and the top surface presents a thick, three-dimensional appearance regardless of the direction of light falling thereon. That is, the key top, being low-profile, looks thick.
