ABSTRACT:
A contact arrangement for a vacuum switch having a switch axis along which switch contacts move. Two identically configured switch contacts are relatively movable opposite to one another along the switch axis. Each switch contact includes: a contact pin for connecting the switch contact with a switch terminal; a contact plate; and a coil body for generating an axial magnetic field. The coil body has at least one winding section extending circumferentially parallel to the contact plate and has a first end connected with the contact plate and a second end connected by an approximately radial conductor section with the contact pin. The side of the winding section facing the contact plate lies continuously against the contact plate and is connected with the contact plate in a conductive manner over the entire length of the winding section. Mutually adjacent winding sections of the two switch contacts lie on top of one another with respect to the switch axis so that the first and second ends of one of the contacts lie above the second and first ends, respectively, of the other of the contacts.
