(54)	High current switch contacts

(57) @ A contact for an electrical switch, more especially a vacuum switch, having a cup-shaped body member with inclined slots in at least the side walls, and a disc having a central boss which provides the contact making surface mounted on the rim of the body member. Such a contact causes the current to move in a manner which generates both axial and transverse magnetic fields tending both to diffuse the arc and to rotate it around the contact.
