In the conventional keyboard structure, the printed circuit board was curved and the switch terminals were attached by soldering, so when soldering, the terminals may not be completely soldered due to the force acting downward on both ends of the board. Also, if some force was applied to the printed circuit board from below, the switch could come off the panel or be soldered at an angle. Therefore, the studs are fitted into the panel and placed between the panel and the printed circuit board. The printed circuit board is fixed to the panel by screwing a screw for fixing the printed circuit board to the stud from the bottom surface of the printed circuit board.
