Both ends of the switch housing 1 are fixedly connected with a plurality of stationary contact pieces 2, and the plurality of stationary contact pieces 2 are arranged in an array; both sides of the switch housing 1 are fixedly connected with a plurality of positioning blocks 3, and the plurality of positioning blocks 3 are arranged in an array; the assembly body 6 is arranged inside the switch housing 1, and a plurality of mounting grooves 11 are provided inside the assembly body 6, and the plurality of mounting grooves 11 are arranged in an array, and both ends of each mounting groove 11 are fitted and connected with an elastic member 12, and one side of each elastic member 12 is fitted and connected with a moving contact 13, and the middle part of each moving contact 13 is fitted and connected with the middle inner wall of the mounting groove 11, and both ends of each elastic member 12 and the moving contact 13 are fitted and connected with one end of the stationary contact piece 2 through the assembly body 6, and one end of the assembly body 6 is fixedly connected with a joint 10, and the outer side of the joint 10 is provided with a connecting groove 4, and the connecting groove 4 is provided in the middle part of one end of the switch housing 1.

[0028] During operation, the multiple elastic members 12 and the moving contacts 13 are respectively inserted into the interior of the installation grooves 11, so that the multiple elastic members 12 and the moving contacts 13 are fixed inside the component body 6. Then the component body 6 is placed inside the switch housing 1, and the multiple moving contacts 13 are placed on one side of the static contact piece 2, and then the connector 10 is connected to the transmission shaft through the connection groove 4, and the rotation of the transmission shaft can drive the component body 6 to slide inside the switch housing 1. Then the top switch housing 1 is covered on the top of the bottom switch housing 1, so that the two switch housings 1 are closed, and then the positioning blocks 3 are used to facilitate the positioning and installation of the two switch housings 1, so that the multiple static contact pieces 2 are horizontally arranged on both sides of the component body 6. And through the sliding of the component body 6, the elastic members 12 and the moving contacts 13 can be driven to move inside the switch housing 1, so that one end of the static contact piece 2 can be inserted between the elastic members 12 and the moving contacts 13, so that the current between the two static contact pieces 2 at both ends of the elastic members 12 and the moving contacts 13 flows. Then, the elastic member 12 and the moving contact 13 are separated from the stationary contact piece 2 by the reverse movement of the assembly body 6, so that the current is disconnected. In the above manner, because the moving contact 13 is a sheet contact, the contact area is increased, the current is increased, the cost of raw materials can be saved, and it is convenient for the staff to install and disassemble, thereby improving the practicality of the contact assembly.

[0029] Further, such as Figure 2 and Figure 3 As shown, a positioning hole 7 is provided in the middle of the component body 6, and a positioning rod 8 is slidably connected inside the positioning hole 7.

Then, by using multiple limit blocks 14 fixed on the outside of the component body 6 and the contact between the limit blocks 14 and the limit plate 5, the movement range of the component body 6 can be limited, so as to prevent the connection between the contacts from being misaligned during the movement of the component body 6, prevent the current flow efficiency from being affected, and improve the service life and practicality of the structure.

[0031] Further, such as Figure 5 and Figure 6 As shown, first slots 15 are provided at both ends of the inner wall of each mounting slot 11, and both ends of the inner wall of each first slot 15 are snap-connected with both ends of the outer wall of the elastic member 12. Two second slots 16 are provided in the middle of each mounting slot 11, and the inner wall of each second slot 16 is snap-connected with the middle outer wall of the moving contact 13, and both ends of each second slot 16 are fixedly connected with arc blocks 18.

[0032] During operation, the moving contact 13 is inserted into the interior of the installation groove 11 in an inclined manner, and then the moving contact 13 is rotated so that the moving contact 13 is arranged horizontally on the outside of the second card slot 16. Then, the two ends of the moving contact 13 are pressed so that the blocks 17 on both sides of the moving contact 13 are stuck on both sides of the second card slot 16, so that the moving contact 13 is fixed inside the second card slot 16. Then, the elastic member 12 is placed at both ends of the installation groove 11, and the two sides of the elastic member 12 are inserted into the interior of the first card slot 15. The two sides of the elastic member 12 are engaged with the inner walls of the two ends of the first card slot 15, so that the elastic member 12 is fixed at both ends of the installation groove 11. The above method is adopted to facilitate the installation and removal of the elastic member 12 and the moving contact 13 by the staff, and improve the installation efficiency of the structure. And the arc block 18 can prevent the static contact piece 2 from being stuck when connecting with the elastic member 12 and the moving contact 13, thereby improving the use efficiency and service life of the structure.

[0033] Working principle: The moving contact 13 is inserted into the installation groove 11 in an inclined manner, and then the moving contact 13 is rotated so that the moving contact 13 is arranged horizontally on the outside of the second card slot 16.

By means of the engagement between the two sides of the elastic member 12 and the inner walls of the two ends of the first card slot 15, the elastic member 12 is fixed at both ends of the installation groove 11, so that multiple elastic members 12 and the moving contact 13 are fixed inside the component body 6. Then, the component body 6 is placed inside the switch housing 1, and the positioning rod 8 is inserted into the positioning hole 7, and one end of the positioning rod 8 is inserted into the slide groove 9, and then the joint 10 is connected to the transmission shaft through the connecting groove 4, and the rotation of the transmission shaft can drive the component body 6 to slide inside the switch housing 1. Then, the top switch housing 1 is covered on the top of the bottom switch housing 1, so that the other slide groove 9 is sleeved on the outside of the other end of the positioning rod 8. The contact between the limit block 14 and the limit plate 5 can be used to limit the movement range of the component body 6. And through the sliding of the component body 6, the elastic member 12 and the moving contact 13 can be driven to move inside the switch housing 1, so that one end of the static contact piece 2 can be inserted between the elastic member 12 and the moving contact 13, so that the current flows between the two static contact pieces 2 at both ends of the elastic member 12 and the moving contact 13.
