The main parts include terminal palms, fixed & moving contact, operating arm insulator, insulator post, operating arm, axis of rotation and rotating lever and so on.

Terminal palm is composed of rotation and frame with angle steel welded, which have six insulators, two sets for a pole. Three-phase operation insulators which operate the knife close or open are installed on the axis of rotation. Operating arm drives axis of rotation to make the separate the knife from contacts when it opens. It even drives axis of rotation to make the insulator pull the knife move down and rotate to closed position when it closes.
