FIELD: electricity. ^ SUBSTANCE: device comprises movable magnetic element (40, 41), moved between three positions, which correspond to three conditions of electric splitter (1), and includes at least one permanent magnet (400, 401, 410), which creates magnetic field with lines (L) of magnetic field to control two microswitches (2a, 2b) under action of magnetic effect. In each position of magnetic device (40, 41) both microswitches are changed to open and closed position to produce combinations that accurately reflect one of three conditions of electric splitter (1). ^ EFFECT: improvement of device. ^ 14 cl, 23 dwg |
