As shown in fig. 1-8, a switch 100 according to an embodiment of the present invention includes a revolving beam 1, a plurality of fixed beam sets 3 and a driving system 4.

Specifically, the revolving beam 1 is suitable for being fixed on the ground through a revolving support 2, the revolving beam 1 is rotatably connected with the revolving support 2 through a joint bearing 6, at least one trolley 5 is arranged at the bottom of the revolving beam 1, and wheels 51 are arranged at the bottom of the trolley 5. The fixed beam sets 3 are arranged at intervals in the rotating direction of the revolving beam 1. In the description of the present invention, "plural groups" means two or more groups. Each set of fixed beams 3 comprises two fixed beams 31 arranged oppositely in the radial direction of the slewing bearing 2, and both ends of the slewing beam 1 are suitable for rotating to be in butt joint with the two fixed beams 31 of one of the fixed beam sets 3 when the switch 100 is switched.
