Abstract
A linear actuating earthing switch configuration that moves movable contacts using linear motion in a single axis. The earthing switch includes a frame with a rail on a slide wall. A sliding carriage slides on the rail in a linear direction, the sliding carriage including a plurality of movable contacts. A stored energy element provides a linear expansion force between the frame and the sliding carriage when the earthing switch is in an open position.
