A caster switching mechanism for installation in a footboard of a scooter is used to control, through a switch pivotally connected with the footboard, whether a wheel seat is rotatable relative to footboard. When the switch is located at a restricted position where the wheel seat is stopped by the switch, the wheel seat is prohibited from rotation relative to the footboard such that a wheel that is rotatably mounted to the wheel seat can roll along one direction only. When the switch is located at an unrestricted position where the switch is separated from the wheel seat, the wheel seat is rotatable relative to the footboard such that the wheel can roll along any direction corresponding to the orientation of the wheel seat.
