Abstract

La présente invention concerne un voyant renseignant sur l'état d'un connecteur électrique. Ce voyant se compose d'un source lumineuse (30), disposée dans le socle (22) d'un connecteur électrique, qui, en brillant au travers de la prise de connecteur (40) et du socle (22) non opaques, renseigne sur l'état de la connexion électrique. La présente invention concerne également un procédé permettant de placer une source lumineuse (30) dans un connecteur électrique, de façon que cette source, par son éclat au travers d'une prise de connecteur (40) non opaque, renseigne visuellement sur un état.
