<p>PURPOSE:To obtain a switching device for facilitating a reduction in size and a grounding operation of an entire device and stably interrupting a large current without increasing a mechanical load of a movable contact driving system. CONSTITUTION:A power source side terminal 2, a load side terminal 3, a power source side ground terminal, a load side ground terminal 5 are mounted at a wall of a sealed vessel 1 in a penetrated and sealed state, a breaker 7 for interrupting a main circuit 8 to connect the terminal 2 to the terminal 3 and a disconnector 6 are arranged in the vessel 1, a power source side ground terminal 4 is intermittently connected to a power source side from the disconnector 6, and a power source side ground terminal 5 is intermittently connected to a load side from the disconnector 6.</p> |
