When the electrode is normally operated, the first moving contact is in contact with the first fixed contact, the second moving contact is in contact with the second fixed contact, when the electrode is disconnected, the second moving contact is disconnected with the second fixed contact firstly, the first moving contact is continuously contacted with the first fixed contact under the action of the spring, so that electric arc cannot be generated when the second moving contact is disconnected with the second fixed contact at this time, then the second fixed contact is continuously descended, the first fixed contact is also separated from the first moving contact, and when the first moving contact is separated from the first moving contact, the electric arc and a large amount of heat can be generated.

In the above technical solution, preferably, a second stopper is disposed on the first movable contact and located on the other side of the baffle.

The utility model discloses following beneficial effect has: when water pours into when the cubical switchboard is located, the floating body floats on the surface of water under the buoyancy effect of water, and the floating body can stimulate the elastomer simultaneously, lets the elastomer form the membrane of round water proof, and water can't permeate through in the membrane enters into the cubical switchboard, can effectively avoid the cubical switchboard to be flooded by water, and the cubical switchboard is still fixed subaerial simultaneously, consequently also can not empty.
