Abstract
A vacuum switching arrangement is provided with contacts formed of an annular member and a diametrical web which is connected to a lead-in pin. Arms are provided at each of the contacts for coupling a contact plate to the annular member. The arms are arranged orthogonally distal with respect to the transverse web. The contact plate has an outside diameter which corresponds approximately to the inside diameter of the annular member. The contacts in accordance with the invention are easily manufactured and produce an axial magnetic field on the entire contact area with a polarity which changes from quadrant to quadrant. Such contacts are particularly suited for use in circuit breakers.
