Load switch

Abstract

The invention provides a load switch, and relates to the technical field of switches. The load switch comprises a bearing main body, a movable contact piece, a static contact assembly and an arc extinguishing assembly. The movable contact is rotatably arranged on the bearing main body. The static contact assembly is fixedly arranged on the bearing main body; the movable contact is used for cooperating with the movable contact to realize switching-on and switching-off. The arc extinguishing assembly comprises a cylinder body, a piston and an air blowing assembly; the cylinder body is fixedly connected to the bearing main body; the piston is movably arranged in the cylinder body, and the piston is connected with the movable contact piece; the air blowing assembly is arranged on the cylinder body, an air blowing channel facing the static contact assembly is arranged on the air blowing assembly, and the air blowing channel is communicated with the internal space of the cylinder body; when the movable contact piece and the static contact assembly achieve opening, the movable contact piece is used for driving the piston to move in the cylinder body, and air in the cylinder body is exhausted from the air blowing channel. The load switch provided by the invention can improve the technical problem of poor arc extinguishing effect in the prior art.
