The invention discloses a multi-path control system applied to a high-voltage phase-selection closing switch. The system comprises a plurality of permanent magnet vacuum switches. Each pole of permanent magnet vacuum switch is composed of four switch units, each permanent magnet vacuum switch comprises a permanent magnet operating mechanism, and a front end of each permanent magnet vacuum switch is provided with an upper computer, a central intelligent phase selection controller, a plurality of photoelectric converters, a plurality of four-way drivers, an isolation transformer, a filter, an energy storage capacitor and an intermediate relay. One photoelectric converter is connected with one four-way driver, and the four-way driver controls one permanent magnet vacuum switch. According to the system, the permanent magnet vacuum switch of each pole can be intelligently controlled to independently complete opening and closing actions, and a three-phase current can be controlled to appearat any required position
