Abstract
1334549 Vacuum switches SIEMENS AG 18 Dec 1970 [19 Dec 1969] 60339/70 Heading H1N A circuit breaker, especially of the vacuum switch type, has disc shaped contacts 8, 15 on the surface of which are spirally mounted ferromagnetic members 10, 17, which cause the rotation of any arc produced between the contacts. The contacts have raised edge portions 9, 16 on one side of the contacts and the ferromagnetic members are mounted on the reverse side of the contacts by means of insulating adhesive or by soldering.
