Classification: CPC H | IPC H

Claim 14:
15. A high-voltage electric power switch comprising:
a sealed container housing a dielectric gas comprising at least 60% carbon dioxide;
a male electric contact located within the container comprising a metallic pin carrying a male carbon electrode;
a female electric contact located within the container comprising a metallic pin receiver carrying a female carbon electrode positioned to receive the metallic pin within the metallic pin receiver;
an actuator for driving the male or female electric contact along an axial direction for opening and closing a current path for an electric power line through the male electric contact and the female electric contact;
the male carbon electrode and the female carbon electrode forming an arc gap for the current path during the opening and closing of the current path;
wherein the male carbon contact comprises a shape preventing or mitigating physical contact with the female electric contact when the actuator drives the metallic pin into physical contact with the metallic pin receiver;
wherein the female carbon electrode comprises a shape preventing or mitigating physical contact with the male electric contact when the actuator drives the metallic pin into physical contact with the metallic pin receiver.
