A body weight support system includes a support track configured to movably suspend a trolley therefrom. A power rail of the system is coupled to the support track and is in electrical contact with the trolley. A switch included in the system has a support track portion and a power rail portion. The switch is configured to transition between a first configuration, in which a first portion of the support track and the support track portion of the switch define a first path, and a second configuration, in which a second portion of the support track and the support track portion of the switch define a second path. The trolley is configured to receive a flow of electric power from at least one of the power rail or the power rail portion of the switch that is operable to move the trolley along the first path or the second path.
