As shown in fig. 3 to 6, the switch 200 includes the switch running gear 100, the first rail beam 210, the second rail beam 220, the translation beam 150, the rotation beam 230, and the carrier beam 240, wherein: the translation beam 150 and the rotation beam 230 are disposed between the first track beam 210 and the second track beam 220 to form different driving channels; the bearing beam 240 is connected between the first track beam 210 and the second track beam 220, and the running rail 160 is arranged on the bearing beam 240; the first end of the rotation beam 230 is connected to the translation beam 150, and the second end of the rotation beam 230 is provided with a rotation shaft, and the rotation beam 230 is configured to be rotatable around the rotation shaft. Illustratively, the second end of the rotating beam 230 is coupled to the switch fixed beam 250 via a rotating shaft. Illustratively, the first rail beam 210 is a curved rail beam and the second rail beam 220 is a straight rail beam.

In the embodiment of the present application, as shown in fig. 6, the switch running device 100 can drive the translation beam 150 to move, and can form different running channels in cooperation with the rotation beam 230. For example, the extending direction of the running rail 160 is set to be the x direction, and the y direction is perpendicular to the x direction, that is, the switch running device 100 can drive the translation beam 150 to move along the x direction, at this time, because the translation beam 150 is connected with the rotation beam 230, the translation beam 150 drives the rotation beam 230 to rotate, and the rotation beam 230 also drives the translation beam to move along the y direction until the switch running device 100 moves to the target position, so as to form a running channel.

The embodiment of the application also provides a track system which comprises the turnout.
