Beschreibung
Zusammenfassung:	Disclosed is an operating button, comprising a light source (10), a push rod (20) and an operating head (30). The light source (10) can output light rays. The push rod (20) is provided with a diverging lens (22) and the operating head (30) is provided with a condensing lens (32). The optical center of said diverging lens (22), the optical center of said condensing lens (32) and said light source (10) are in the same line. The operating button has only one diverging lens (22) and one condensing lens (32) on the propagation light path of the light rays generated by the light source (10), and therefore the distance between the light source (10) and the diverging lens (22) can be conveniently adjusted and the brightness of the light rays irradiated by the operating button is improved without causing any light spot.
