An arc blow-out switch is formed of a plurality of extinguishing units arranged in tandem, each including a movable compression cylinder and a stationary compression piston arranged in the compression cylinder. Axially aligned insulating cylinders surround each extinguishing unit. The arc blow-out switch further has a rod arrangement disposed within the insulating cylinders and connected to the compression cylinders for moving the latter as a unit to effect circuit making and circuit breaking operations. |
