FIELD: city rail transport. ^ SUBSTANCE: according to invention, solenoid coils are installed coaxially in sealed housing. Cores are fitted for displacement in holes of solenoid coils. Said cores are interconnected and mechanically connected with at least one of switch tie-rod by means of guide mechanism. Switch tie-rod is installed outside sealed housing. Guide mechanism is provided with shaft passed through wall of housing from side of switch tie-rod. Guide mechanism shaft is installed in said housing by means of seal with possibility of turning relative to its longitudinal axis. Cores are made in form of common part with central cross slot. Two radial bars are installed on shaft of guide mechanism. One of bars is arranged inside sealed housing and is movable coupled with cores by pivot installed on said bar and passed through said slot. Other bar is arranged outside sealed housing, being hinge coupled with switch tie-rod. ^ EFFECT: provision of universal electric device which can be used in single point and double point switches. ^ 2 cl, 4 dwg |
