The invention discloses an electric-hydraulic switch machine which comprises a hydraulic power unit and multiple switch units. Each switch unit comprises a switch locking mechanism which comprises an oil cylinder, the oil cylinders of the switch units are serially connected and are equal in volume, and the hydraulic power unit drives the oil cylinders to act synchronously. Through a designing mode that the oil cylinders of the switch units are serially connected and equal in volume, synchronous switching of multiple rail junction traction points is realized, and the electric-hydraulic switch machine is quick in switching, high in synchronicity, suitable for switching, locking and indicating of various rail junctions and especially suitable for high-speed rail junctions.
