Abstract (en)
[origin: WO2013175112A1] To control the arc that forms during cut-off in a vacuum bulb, a contact device (10) has been developed, which makes it possible to inflict a rotational motion on the arc, while keeping the arc diffuse. The rotating diffuse arc is obtained in that each electrode (12) of the contact device (10) comprises a solid wafer (20) associated with a base (30) of petal type, the two electrodes mirroring one another.
