なる。With this structure, the switching plate can be freely swung since it is always elastically engaged with the swing center. Moreover, by adjusting the length of the arm part, it is possible to set the spring constant of the part that makes elastic contact with the switching plate to be lower than that of the conventional one, and the pressure change due to wear of the swing support part and dimensional variation in processing. The durability of the switching plate can be improved, and the switching plate can be vibrated due to a shock wave generated when the contact pressure is applied, because the switching plate is always supported and the electrical connection is maintained regardless of the swinging or vibration of the switching plate. Even if there is, the common terminal absorbs this shock wave, so contact failure does not occur. Further, by providing the common terminal with the arm portion, it is not necessary to process the common terminal into a substantially S shape as in the conventional case, and the shape of the common terminal is simple and the processing is easy.
