Abstract

425,345. Electromagnetic switches. KATSCH GES., P., Sommerda, MEYER, E., 22, Langestrasse, Sommerda, Thuringia, Germany, and ISENTHAL, A. W., Ducon Works, Victoria Road, North Acton, London. July 9, 1934, No. 20160. Convention date, July 8, 1933. [Class 38 (v)] A current impulse in a coil 7 causes a steel needle 6 to move out of bridging engagement with two mercury contacts 4, 5, in a vessel 1 and to fall into a vessel 2 arranged at an angle as shown. Here it may bridge two other contacts 4, 5, (shown dotted). A second current impulse will move the needle back again. The vessels may be evacuated.
