Abstract
A vacuum switch with an elongated cartridge comprising a cylindrical housing sealed by two end plates. Inside the cylindrical housing there are two arcing contacts, one stationary and one movable. The stationary contact is securedly affixed to one of the end plates, whereas the other movable contact is mounted to axially slide inside the cartridge. At least two portions of turn are mounted in parallel. Each portion has a first end electrically connected to one of the arcing contacts and a second end electrically connected to the current input strip of the contact. The first and second ends of each portion of turn are electrically connected by a branch-off designed to disperse a part of the main current trough the potions of turn during breaking.
