FIELD: electrical engineering. SUBSTANCE: in compliance with method for closure contacts are moved rectilinearly and in stages. First center of mass of only one contact is displaced, then other contacts are made simultaneously in mutually perpendicular directions with giving rotation to one of contacts with respect to center of mass and synchronization of speeds and accelerations of its rotation by values and directions of relative linear speed of contacts. After this closure is accomplished. For breaking contacts are moved in opposite directions. In this case lag of relative movement of contacts is observed up to moment when there is no gap in structure in direction perpendicular to lines of force of intercontact magnetic field. After this contacts are broken by simultaneous rectilinear translation is mutually perpendicular directions. Device for implementation of method has coaxial cylinders spread along longitudinal axis and connected to bearing elements for reciprocating motion along same axis perpendicular to guide of ball rolling over contacts located on side surfaces of cylinders spring-loaded along common axis. EFFECT: enhanced operational properties. 4 cl, 1 dwg
