1. 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.
