Abstract

522,798. Electromagnetic switches. STANDARD TELEPHONES & CABLES, Ltd. Dec. 16, 1938, No. 36705. Convention date, March 29. [Class 38 (v)] A single magnetising coil 28 is used to control two or more switches each comprising a gastight vessel evacuated or filled with non-corrosive gas and containing a pair of contacts 4, 5 of magnetic material. Energization of the coil 28 causes the contacts 4, 5 to engage each other. The device is also provided with a metal frame 31 adapted to act as an electromagnetic shield. The contact springs may have inserts of platinum at their points of engagement or may be coated or plated with a metal such as gold.
