Abstract
A three-position disconnector switch includes a platform, a power in contact, a power out contact, an earthing contact, and a piston. In a first position, the piston contacts the power out contact and the power in contact. In a second position, the piston contacts the power out contact. In a third position, the piston contacts the power out contact and the earthing contact. The piston moves along an axis to transition between the different switch positions. The power in contact is mounted to the platform, the power out contact is mounted to the platform, and the earthing contact is mounted to the platform.

A three-position disconnector switch, comprising:
- a platform;
- a power in contact;
- a power out contact;
- an earthing contact;
- and
- a piston;
- wherein the platform comprises a dielectric insulating body;
- wherein, in a first switch position, the piston makes an electrical contact between the power out contact and the power in contact;
- wherein, in a second switch position, the piston makes an electrical contact with the power out contact;
- wherein, in a third switch position, the piston makes an electrical contact between the power out contact and the earthing contact;
- wherein the piston is configured to move along an axis of the three-position disconnector switch to transition the three-position disconnector switch to the first switch position, to the second switch position, or to the third switch position;
- wherein the power in contact is mounted to the platform;
- wherein the power out contact is mounted to the platform;
- and
- wherein the earthing contact is mounted to the platform.
