Abstract: An electrical device comprises a printed circuit board, a first contact portion, a second contact portion, a first conductive wall and a second conductive wall. The printed circuit board has a first surface and a second surface, on which the first contact portion and the second contact portion are disposed, respectively. The first conductive wall and the second conductive wall are in electrical contact with the first contact portion and the second contact portion, respectively. The first contact portion and the second contact portion are offset from one another in a direction parallel to at least one of the first surface and the second surface.
