Abstract
Electrical circuit breaker comprising an envelope, a first contact mounted on said envelope, a second contact on said envelope having a surface suitable for cooperating with a surface of said first contact, a movable contact arm group carrying said second contact intended to be brought into surface contact with and separated from said first contact, and drive means for moving said contact arm group closer and away from said first contact, characterized by the combination according to which the arm group of contact comprises a contact contact consisting of a plate-shaped current conducting sheet and a support element of said sheet with which it is in intimate support contact, said sheet having a part as a surface, arranged opposite of said first contact during surface contact between said contacts.
