Further, the insulation limit stop is wrapped in the flexible dust cover, and the flexible dust cover covers the periphery of the lower opening and seals the lower opening.
Further, and this handle is located outside the flexible dust cover.
Furthermore, one end of the fuse forms a fuse connecting post outside the shell through a connecting wire, and the other end of the fuse inside the shell is connected with a V-shaped rod made of conductive metal through the connecting wire.
Further, the fixed contact is communicated to the outside of the shell through a connecting wire, and a contact wiring terminal is formed.
Preferably, the fixed contact is fixedly arranged on the frame plate and is arranged in the shell through the frame plate.
The invention can lead the movable contact to stably abut against the fixed contact when the contact is closed by the acting force of the compression spring so as to connect the circuit, lead the movable contact to be away from the fixed contact along with the movement of the long straight rod when the contact is separated so as to disconnect the circuit, and can ensure the stable state of the long straight rod due to the action of the insulation limit stop block.

Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
As shown in fig. 1 and 2, a two-phase electric switch has a square housing 1, a lower opening 2 for passing a long straight rod 10 is provided below the housing 1, a pull rod connector 9 is provided at the top end of the long straight rod 10, the pull rod connector 9 is located inside the housing 1, an insulation limit stop 11 is further fixedly provided at the lower part of the long straight rod 10, a handle 12 is provided at the end of the insulation limit stop 11, the insulation limit stop 11 is located below the lower opening 2, the area of the insulation limit stop 11 is larger than that of the opening 2 for limiting the position of the long straight rod 10, the insulation limit stop 11 is wrapped in a flexible dust cover 13, one end of the flexible dust cover 13 is fastened on the long straight rod 10 between the insulation limit stop 11 and the handle 12, and the other end thereof is covered and bonded on the lower surface of the housing at the periphery of the lower opening 2, thereby closing the lower opening 2, and the movement of the long straight rod 10 cannot be influenced due to the flexible characteristic of the long straight rod; two V-shaped rods 7 are movably arranged on two sides of the front surface of the pull rod connector 9 respectively, the two V-shaped rods 7 are identical in structure and can swing, as shown in figure 1, one end part of the lower part of each V-shaped rod 7 is a movable contact 14 made of spherical conductive metal, the other end part of the lower part of each V-shaped rod 7 is connected with a telescopic pressing spring 6, the pressing spring 6 is always in a compressed state, two ends of the pressing spring 6 are provided with elastic forces extending outwards, the pressing spring 6 is connected with a hinged part 5 arranged on the inner wall of a shell 1 in a direction of pressing the V-shaped rod 7, the movable contact 14 corresponds to a fixed contact 15 fixedly arranged inside the shell, the fixed contact 15 can be erected inside the shell through a frame plate, the fixed contact 15 is connected with a contact binding post 8 through a connecting wire, and the left and the right sides of the fixed contacts are respectively arranged, the V-shaped rod 7 is made of conductive metal, one end of the V-shaped rod connected with the compression spring 6 is also connected with the fuse 4 through a connecting wire, the fuse 4 is arranged at the top inside the shell 1, and the connecting wire extends outwards to form the fuse terminal 3.
