FIELD: electrical engineering.
SUBSTANCE: claimed device comprises an actuator as a vacuum cartridge 6 connected with the main electric circuit 1, 2, 3 and provided with the rod supporting the cartridge slide contact 9. The device comprises a solid and stiff rocker 12. The latter can turn about two pivots 11, 21 and engage with the said main slide contact 3 at making or breaking the vacuum cartridge at making a connection. The rocker oscillations between two fixed points 11, 21 allows its engagement with the said main slide contact in one direction of displacement and its displacement in the other direction without forward withdrawal.
EFFECT: higher reliability and simplified design.
