Summary
[edit]DescriptionEricsson BC 560 m50 001-02.jpg |
Svenska: Ericssons nya bakelittelefon från 1947 hade mjukare former, fingerskiva av slagtålig termoplast och en lur som var böjd och strömlinjeformad för bästa ergonomi.
Den fick namnet BC 560, modell 50, i Telegrafverkets nät och ersatte år 1950 den tidigare BC 330, modell 33, som standardapparat. Modellen förekom också i andra färgnyanser än svart tillverkad av termoplast. Sammansättningen av apparaten förlades till den nyanlagda fabriken i Karlskrona. I och med denna modell markerades slutet för användningen av bakelit i svensk telefontillverkning. Telefonen på bilden tillhör den samling från Telemuseum som skänktes av TeliaSonera AB till Tekniska Museet 2010. Telefonapparat BC 560, ändstationsapparat för AT-system. Bordstelefon modell m50 av genomskinlig termoplast med apparatsnöre anslutet till väggplint med transparent plastlock. |
