Abstract

Electrical contacts with a reduced section for use in high-voltage switches, the contacts are produced by machining or by extrusion. The contacts are designed to be used outdoors, indoors, in vacuum or in any other inert atmosphere for electrical switching equipment without additional pressure system or with additional pressure system. The contacts can be used in linear movement, radial movement, or any other type of movement or sliding. The contacts can be used in various shapes, such as contact pins or tulip shapes, partial tulips, or rectangular tulips, or they can be used as the single pressure element for the electrical contact. The contacts are designed to cooperate electrically with opposing contact parts. The contacts can interrupt a physical link with an opposing contact or they can remain in constant contact during the operating movement. The contacts are made from aluminum alloys, with or without contact surfaces. A contact assembly can use the same base materials or different base materials. The contacts can be used as an intermediary between copper and aluminum parts in the switch to prevent corrosion due to the electrochemical potential difference of the materials.
