A vacuum interrupter includes a number of insulative tubes having a first open end and a second open end; a first end member secured to the first open end; a second end member secured to the second open end; a fixed contact mounted on a fixed electrode extending through the second end member; a retainer; and a movable contact. The retainer includes a rigid retainer having a plurality of legs and an opening, and an insulative bushing having a smaller opening. The insulative bushing is molded over a portion of the rigid retainer. The smaller opening is within the opening of the rigid retainer and is structured to receive a movable electrode. The movable contact is mounted on the movable electrode extending through the first end member and through the smaller opening. The movable contact is capable of axially reciprocating into and out of contact with the fixed contact. |
