Abstract

1,223,361. Potential divider. SIEMENS A.G. 28 Jan., 1969 [30 Jan., 1968], No. 4734/69. Heading H4R. [Also in Divisions G1 and G4] A potential divider R 1 , R 2 and R 3 has tapping points 1, 2 and 3, connected by respective emitter follower transistors 7, 8, 9, to a common output terminal 17 and emitter load R L . A switch S, which may be at a remote location, supplies a bias -U s to a selected transistor to cause it to conduct, and connect the respective tapping point to the output terminal, while the remaining transistors are held cut off.
