Abstract
A three-position disconnector switch includes an earthing contact, a power out contact, a power in contact, and a piston. The power out contact comprises first and second parts connected by a leg portion. In a first position, the piston contacts the first part of the power out contact. In a second position, the piston contacts the first part of the power out contact and makes electrical contact with the second part. In a third position, the piston contacts the second part and makes electrical contact with the earthing contact. The piston is configured to move along an axis of the three-position disconnector switch to transition the three-position disconnector switch between the different switch positions.
