Abstract
A key structure includes a light source and a light guiding assembly, a transparent cover, a semi-transparent and semi-reflective mirror, and a reflection mirror disposed above the light source. The light guiding assembly includes a center column and a platform surrounding the center column. A bottom surface of the center column faces the light source. The transparent cover is disposed on the light guiding assembly and covers the center column and the platform. An exterior side wall of the transparent cover has strip recesses surrounding the center column and the platform. The reflection mirror is disposed in the light guiding assembly. The reflection mirror and the semi-transparent and semi-reflective mirror face each other through the transparent cover. A part of light generated by the light source generates an infinity reflection between the strip recesses, the reflection mirror, and the semi-transparent and semi-reflective mirror after passing through the light guiding assembly.
