FIELD: electromechanics.
SUBSTANCE: power supply of coil is generated by aperiodic current that is several times higher at a moment of activation than by magnet keeper confinement. Contacts pressure is several times increased without pulling capacity change. Shared fixed contact is applied.
EFFECT: several times reduction of electrical energy consumption, decrease of contacts resistance, current limiting for contacts switching on and off.
