Patent ID: 8237076

Claim:
A vacuum switch comprising a main circuit vacuum switch accommodated in a first vacuum chamber, an earth switch accommodated in a second vacuum chamber, a first operating rod connected to a movable conductor of the main circuit switch, a second operating rod connected to a movable conductor of the earth switch, and a molding case covering the first and second vacuum chambers and the first operating rod, wherein the operating rods are connectable with an operating mechanism, and the fixed conductors of the main circuit switch and earth switch are connected with bushing conductors, wherein the main circuit switch comprises two vacuum switches disposed separately in respective vacuum chambers confining separate respective vacuums, the movable of the two vacuum switches are electrically connected by means of a transition conductor, and the movable conductors are connected to a stiff transition rod, which is connected to the operating rod, and wherein the movable conductors of the two vacuum switches are operated synchronously via the transition rod.
