ABSTRACT:
An electrical contact breaker has a stationary contact, and a movable contact. The movable contact is connected to a terminal by a flexible conductor. For blowing out the arc formed when the contacts separate under load, there is a blowing means including a winding traversed by the current, and pole pieces directing the magnetic field of the winding to the vicinity of the arc gap. The improvement is that the winding is constituted by at least part of the flexible conductor.
