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.

Push-button switch operating portion with diverging and converging lens

A button includes a housing, an operating portion, a mount, a first pushing rod, a bridge, an elastic member, and a second pushing rod. The mount is mounted in the housing. The first pushing rod is movably disposed in the mount. A bump is formed on the first pushing rod. The bridge and the operating portion are disposed on ends of the first pushing rod. The second pushing rod is movably disposed on the bridge and is effected by the elastic member. A step is formed in the housing and is located between the mount and the bridge. The elastic member is disposed on the first pushing rod and is located between the bump and the step. The first pushing rod is slidable relative to the mount under the effect of the operating portion or the elastic member, and drives the bridge and/or the second pushing rod to move.
