Abstract

384,101. Switch cases. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Dec. 23, 1931, No. 35617. Convention date, Dec. 23, 1930. [Class 38 (v).] To prevent electrical apparatus, such as a wireless receiving set, from being operated when the casing is open. the main switch is mounted on the movable lid b and the fixed contacts t are connected in circuit by lugs a which abut on to spring contacts f connected to the mains and the apparatus. Thus on opening the lid, the circuit is broken at a, f.
