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.

An indicator lamp is disclosed, in particular for an electromechanical command device. The indicator lamp includes a housing and a light source, which is arranged in the housing and emits light when supplied with energy. Furthermore, a lens arrangement is provided, including a first lens unit, which is arranged in the propagation direction of the light emitted by the light source and is built such that light beams emitted by the light source exit substantially parallel from a side of the first lens unit that faces away from the light source. The lens arrangement includes a second lens, which is arranged on the side of the first lens unit that faces away from the light source and is built such that some of the light beams exiting from the first lens unit are directed with respect to the propagation direction towards a transparent side surface of the housing.
