したものである。As explained above, the switch action of the present invention is achieved by attaching the first conductive leaf spring and the second conductive leaf spring that exert the switch action to both sides of the printed wiring board, and parallel to the printed wiring board. Since the switching member for switching the switch is configured to be displaced parallel to the printed wiring board, it has the advantage that the length in the direction perpendicular to the board can be shortened. Therefore, the present invention is suitable for ultra-miniaturization, particularly thinning, of electronic equipment such as tape recorders.
