The controller that operates opening and closing of swing door of a vehicle. TOGGLE SWITCH’s continuous maintain control rotates D.C MOTOR back and forth, and the turning force of gear in main board decelerates. The turning force, through DRIVE SHAFT, reaches linkage and door arm and enables opening and closing of the DOOR. Depending on the lading condition between door operation ranges, the speed rate of opening and closing is controlled by IC circuit.
