METHOD TO MANUFACTURE MAGNETICALLY OPERATED SEALED CONTACT Russian patent published in 2012 - IPC H01H11/04 B82B3/00 

FIELD: electricity.

SUBSTANCE: in a magnetically operated sealed contact with ferromagnetic contact parts arranged in a glass body, on a contacting surface of contact parts due to bombardment by particles with energy of 300-10.000 eV and dose of at least 10¹⁹ cm^-2 create nano- and microledges.

EFFECT: higher stability of its operation under various modes within a long period of time, simplified technology of contact making, elimination of effect from ingress of foreign nano- and microparticles at contact properties, in some cases elimination of precious metals use in a contact coating and exclusion of dirty and complicated galvanic technologies of coat deposition.
