Abstract
A rotary switch for a people mover guideway having a predetermined path, guidebeam and electric rail configuration, routes a transit car having electric power signal collectors from one entry guideway path to either of two exit guideway paths or vice versa. The switch has an elongated structural frame provided with guidelines, electric rail and tire path structure on one side compatible with the guideway configuration to provide car routing to one of the two exit paths. The frame further has guidebeam, electric rail and tire path structure on another side compatible with the guideway configuration to provide car routing to the other of the two exit paths. The electric rail structure on each side of the frame includes power rails and signal rails disposed along the respective switch paths of travel for respectively contacting the electric collectors of the transit car. An electric connection arrangement for the switch includes first electric conductors for connecting the switch power rails to the guideway electric power rail circuit and second electric conductors for connecting the switch signal rails to the guideway signal rail circuit. The first and second conductors are bundled t…
