Arcing electrode, more particularly for vacuum switches

A contact assembly for a vacuum switch comprising two electrodes facing each other for taking up arc roots, each of said electrodes including a contact stud having a contact surface and a plurality of plates having narrow surfaces facing the opposite electrode, the plates being separated by gaps whose width is equal to at least the thickness of the plate, and further electrode plates intersecting the first said electrode plates at an angle to form a honeycomb structure at least in proximity to the contact surfaces of the nearest contact stud.
