Helvestine AttorneyFinnegan, Henderson & Farabow ABSTRACT: A switching device for performin operations between a first group of incoming second group 0 representing in a selected code the identification of ing and outgoing line is cludes a plurality of bistable input frames and a plurality of bistable output frames which are actuated in response to a coded input signal. The device also includes a bistable junction rods mounted for transverse mov tive to the bistable input and ou tuated in response to the input signal. The bistable input and output frames and the junction rods operate circuits associated with the bistable frames for selec coming and outgoing lines connected to the ci e, both of ATIONS 179/18 GE, 200/177, 335/112 H04g 3/42, H01h 67/14 179/l8.74, 22; 200/177; 335/1 12 Roger Marcel Chaveneaud Levallois-Perret; Georges J anoska, Courbevoi France [21] Appl.
