Abstract

High-voltage circuit breaker comprising an elongated casing filled with a gaseous arc-extinguishing medium, said casing comprising two cooperating arcing contacts and two cooperating main contacts (10), which during an opening operation separate earlier than the arcing contacts. According to the invention one of the main contacts (10) consists of one end portion of a metal tube (12) which is secured to the casing. This end portion is formed by pressing (bulging) and slotted in such a way as to form a plurality of contact fingers (14) integral with the tube. The contact fingers may be surrounded by a tubular metal sleeve (15) serving as a field-equalizing shield. This sleeve may also serve as a holder and counter-support for one or more auxiliary springs (17) arranged between the sleeve and the contact fingers. By allowing the free end portion of the sleeve (15) to surround the end portions of the contact fingers, the contact fingers are furthermore prevented from being bent too far inwards. <MATH>
