A closure mechanism for maintaining a foldable table in a closed configuration and for allowing opening thereof. The system includes an AFS actuator for providing a steering assist signal for stability control purposes, and a VES actuator for providing resistance against turning of the steering wheel. The lithographic apparatus also includes a substrate table configured to hold a substrate and a projection system configured to project the patterned beam onto a target portion of the substrate to form a patterned image on the substrate. The holding unit is attached to the communication unit so as to be movable to a position where the holding unit covers the connector in a stored state, and movable to a position where the holding unit exposes the connector in a used state.
