A switch structure on the sidewall of a circuit board for an electronic device and manufacturing methods of the circuit board are provided. The switch structure includes a circuit board, a plurality of conductive portions, and a movable unit. The conductive portions are formed on a sidewall of the circuit board and electrically insulated from each other. The movable unit is disposed corresponding to the conductive portions to electrically connect or disconnect the plurality of conductive portions to achieve the switch function. The switch structure utilizes the structural design of the circuit board to reduce the space on the circuit board preserved for a circuit board switch.
