A group-operated switching system for multi-phase electrical transmission lines including a number of inline axial switches for opening and closing circuits to control electrical flow through the transmission lines. The switches include axially mounted load break vacuum interrupters and are mechanically and electrically isolated from each other and from a control box. The control box communicates with the inline switches via RF communications. Power for the switch electronics and operations can be provided from line power, a battery, or a capacitive source.

A switch for a medium voltage or high voltage switchgear includes: a first fixed contact; a second fixed contact; a moveable contact; at least one flexible link; and a contact drive. In an on state of the switch, the moveable contact is in a position that connects the first fixed contact to the second fixed contact. In an off state of the switch, the moveable contact is in a position where the first fixed contact is not connected to the second fixed contact. The at least one flexible link is connected to the moveable contact. The at least one flexible link engages with the contact drive. The contact drive pulls the moveable contact via the at least one flexible link and pushes the moveable contact via the at least one flexible link. Activation of the contact drive in a first mode moves the moveable contact.

A three-position disconnector switch includes: an earthing contact; a power out contact; a power in contact; a first piston; and a second piston. In a connected switch position the first piston makes an electrical connection with the power out contact and the second piston makes an electrical connection with the power out contact and the power in contact. In a disconnected switch position the first piston makes an electrical connection with the power out contact and the second piston makes an electrical connection with the power out contact. In an earthed switch position the first piston makes an electrical connection with the earthing contact and with the power out contact and the second piston makes an electrical connection with the power out contact.
