Luminous marker disc, applicable to automatic telephone devices, characterized by carrying the figures in phosphorescent material, either by applying them to matter with these properties, or because all the disc material is phosphorescent and has the background painted to avoid phosphorescence in places that have to remain dark, so that in the darkness these figures are perfectly legible.
