The paper presents experimental tests results of magnetic field
distribution for highcurrent switch. Provided tests show influence of switch shape on field distribution to obtain sustained vitality of vacuum switch. The method shown in the paper let obtain all components of magnetic induction vector. There is aspired to gain the highest value of axial component designing switches shape . It warrants favorable influence on fixity and turn off ability of switch system. There are lower values of peripheral and radial components making bipolar field in space between switches. (The Measurement of magnetic field in highcurrent unipolar switches).
