Abstract

La présente invention concerne un commutateur à courant permanent comportant au moins deux plots de contact 2 et 3. La présente invention consiste dans le fait que la surface de contact 8 de l'un des plots de contact 3 est réalisée en forme de calotte sphérique et que la force de contact F est de 500 N au minimum. Ce commutateur à courant permanent est avantageusement d'un mécanisme souple et à fonctionnement sûr, et il peut être équipé de plots de contact qui sont uniquement fabriqués en un matériau conduisant normalement l'électricité. Les commutateurs à courant permanent correspondant à ce qui vient d'être dit conviennent notamment pour court-circuiter des aimants supraconducteurs.
