It consists in a glass tube filled with metal filings which acts as an insulator when placed in a circuit comprising a battery and a galvanometer. However, if an electric spark is created some distance away, it becomes a conductor and lets the current pass into the circuit. When the tube is tapped lightly it becomes an insulator again and interrupts the current. 3, record 1, English, - Branly%20detector

Il s'agissait, à l'origine, d'un simple «petit tube de verre qui ressemblait à un thermomètre» mais qui était rempli de limaille de fer. Branly découvrit que les ondes électro-magnétiques pouvaient provoquer à distance la cohésion des particules de limaille contenues dans le cohéreur, ce qui permettait à un courant électrique de la traverser. 4, record 1, French, - coh%C3%A9reur
