Abstract

876,578. Switch contacts. TELEFUNKEN G.m.b.H. Dec. 11, 1957 [Dec. 11, 1956], No 38458/57. Class 38 (5). [Also in Group XL (c)] In a turret tuner (see Group XL (c)) rotor contacts 10 may take the form of bifurcated rivets. Stator contacts 19 may consist of strips of spring material bent into a ring. Alternatively, leaf spring stator contacts may be used.
