Abstract

Improvements introduced in the high-voltage circuit breakers, comprising a fixed contact or a mobile contact provided with an arc contact and having an open position and a closed position, characterized in that the fixed contact comprises a contact semi-mobile that joins it in a closed position, on the one hand to the mobile contact and on the other hand to the arc contact, said arc contact being mobile in relation to the mobile contact and maintained contact with the mobile contact by a pressure spring supported by the movable contact and which, during the passage from the closed position to the open position, the semi-mobile contact and the arcing contact, remain fixed first, and then separate, the semi-mobile contact of means of solicitation and the arc contact being requested by the mobile contact.
