CONSTITUTION:When the edge 21 of a movable plug 9 is withdrawn, a cover 24 closes an outlet 23 by the excitation of a spring. When the edge 21 is protruded, a cover 27 automatically closes a fixed socket 8 in conjunction with it. When one is in use, the other is not kept opened, an electric shock accident can be prevented. A movable terminal bed 34 is movably fitted to integrally stacked plates 17 and 18, a movable terminal 39 is fixed on the lower face in touch with circuits 40 and 41 on the substrate 18, an electric circuit 5 is connected to the fixed socket 8 or the movable plug 9 according to the usage state. |
