Lampe téléphonique Lilliput

Year 1977.

Polish company POLAM.

Telephone lamps find wide application in telephone exchanges where they act as indicators to enable visual control of the number of lines in operation and the connections made. They can also be applied as resistors. When mounted in series with the circuit, they serve to keep a check on the proper functioning of the respective telephone lines.

Thanks to Péter Horváth (Fénymúzeum – Museum of Electrical Lighting and Industrial History, Hungary) who donated this lamp.
