An electro-mechanical switch, constructedsubstantially as described, in combination withtwo or more electro-magnets, placed in two ormore distinct branches, 15 and 16, of the cir-cuit containing said switch, all connected andoperated substantially as described. 2. The springs d d, in combination with thevibrating armature and the points c c, formaintaining the continuity of the same circuit,substantially as set forth. THOMAS A. EDISOX. Witnesses: W. Hatjff, E.
