The invention provides a simple conversion type electro-hydraulic switch machine which comprises a bottom shell, an actuating rod assembled in the bottom shell, an actuating piece connected with the end part of the inner end, arranged in the bottom shell, of the actuating rod, and a hydraulic power assembly or a motor speed reducer group which is arranged on one side in the bottom shell and is sequentially arranged in the direction parallel to the actuating rod, a fixed assembly part is fixedly mounted on the inner side of a side plate of the bottom shell; the hydraulic power assembly comprises a valve body integrated block, a hydraulic oil pump and a motor which are sequentially arranged on one side of an inner cavity of the bottom shell in the length direction of the action rod. The hydraulic oil pump is fixedly installed in an oil tank of the valve body integrated block. A hydraulic rod is connected between the action piece and the fixed assembly piece and is connected with the hydraulic oil pump through a pipeline; or a lead screw is connected between the action piece and the fixed assembly piece, and the lead screw is connected with the motor speed reducer set through a transmission belt or meshed with the motor speed reducer set through a gear. And through further modular improvement, rapid conversion between hydraulic drive and electric drive is achieved, and the maintenance cost is reduced.
