MAGNETICALLY-OPERATED SWITCHBOARD Russian patent published in 2012 - IPC H01H36/00 

FIELD: electricity.

SUBSTANCE: invention is related to high-frequency equipment of radio-frequency signal switching and may be used as a non-volatile antenna switchboard, which comprises a casing with a magnetically-operated contact (sealed contact reed relay) and a permanent magnet made as capable of angular displacement in the vertical plane, installed in it. The switchboard is equipped with additional sealed contact reed relays installed in radial channels made in the casing. Electric outputs of one of the sealed contact reed relay contacts have a common connection point. Electric outputs of the other contact of sealed contact reed relays are designed for connection to antenna inputs. Electric outputs of each sealed contact reed relay form a coaxial line together with the casing for passage of a radio frequency signal as sealed contact reed relay contacts close. The permanent magnet is made as capable of circular rotation around the axis of the magnet suspension.

EFFECT: increased number of switching channels and expansion of switchboard functional capabilities.
