Abstract
An operating button includes a light source, a push rod with a diverging lens, and an operating head with a condensing lens. The optical center of the diverging lens, the optical center of the condensing lens and the light source are in the same line such that light rays generated by the light source pass through the diverging lens and the converging lens before exiting the operating head as parallel light.
