[0029] Embodiment 1

[0030] See also Figures 1 to 6 The utility model provides a technical solution: an electrical control switch, comprising a switch body 1 and a switch housing 2, wherein the switch housing 2 is pluggably fixed to the front end of the switch body 1;

[0031] The sealing slide cover 6 is fixed in a groove on the surface of the switch housing 2 to provide a dustproof seal for the switch housing 2;

[0032] A control rod 9, which is fixedly connected to a rotating handle 8 of the switch body 1, and plays a role of unilateral reversal of the current in the switch body 1;

[0033] The electrical control switch has good dust resistance and sealing properties. During transportation and packaging, the possibility of dust intrusion can be reduced by sliding and closing the sealing slide cover 6. At the same time, the switch is a rotary reversing structure and can only rotate in one direction. The one-way rotation operation mode is less prone to misoperation than the button type, reducing the possibility of misoperation in subsequent use.

[0034] Embodiment 2

[0035] On the basis of the first embodiment, the switch housing 2 comprises a housing shell 3, a slide groove 4, a wire outlet hole 5 and a sealing slide cover 6. The surface of the housing shell 3 is provided with a slide groove 4. The slide groove 4 is provided with a plurality of groups and symmetrically arranged at the four corners of the surface of the housing shell 3. Each group of slide grooves 4 is provided with a through wire outlet hole 5. The slide groove 4 is slidably connected with a sealing slide cover 6.

[0036] The sealing slide cover 6 includes a slide cover body 14 and a connecting rod 15. The slide cover body 14 is provided with a plurality of groups, which are fixed to each other by the connecting rod 15.

[0037] The sliding cover body 14 includes a pressing block 16, a sliding rod 17 and a limiting protrusion 18. One side of the pressing block 16 is rotatably connected to one end of the sliding rod 17, and the other end of the sliding rod 17 is rotatably connected to the limiting protrusion 18. The sliding rod 17 and the limiting protrusion 18 are provided in two groups and are symmetrically arranged on both sides of the pressing block 16.

[0038] After manufacturing is completed, the assembler can slide the sealing slide cover 6 into the wire outlet hole 5 to reduce the intrusion of dust during transportation. When sliding, the pressing block 16 is pulled toward the side of the wire outlet hole 5, and the pressing block 16 drives the sliding rod 17 and the limiting protrusion 18 to move in the slide groove 4. Since multiple groups of pressing blocks 16 are fixed by the connecting rod 15, when a single group of pressing blocks 16 moves, it will drive the remaining pressing blocks 16 to move together, saving time and effort. However, the sealing slide covers 6 in the four groups of slide grooves 4 do not generate linkage with each other. When in use, if only one group of wire outlet holes 5 is needed, only the corresponding sealing slide cover 6 needs to be slid and pulled out, and the remaining groups of wire outlet holes 5 can be closed to reduce the intrusion of dust.

[0039] Embodiment 3

[0040] On the basis of the first embodiment, the switch body 1 includes a front baffle plate 7, a rotating handle 8, a control rod 9, a sealed housing 10, a heat dissipation fan 11, a heat dissipation hole 12 and an output terminal 13. The front end of the front baffle plate 7 is rotatably connected with the rotating handle 8, one end of the control rod 9 passes through the front baffle plate 7 and is fixedly connected with the rotating handle 8, the other end of the control rod 9 passes through the sealed housing 10 and is rotatably connected with the sealed housing 10, the front baffle plate 7 and the sealed housing 10 are fixedly connected by bolts, the front end of the output terminal 13 passes through the sealed housing 10 and is fixed inside the sealed housing 10, heat dissipation holes 12 are opened on both sides of the sealed housing 10, and the rear end of the sealed housing 10 is fixedly connected with the heat dissipation fan 11;

[0041] When in use, the heat dissipation holes 12 discharge the heat generated inside the sealed housing 10, and the heat dissipation fan 11 is powered on to blow the heat out of the hole opened at the front end of the switch housing 2. When installing the external cable, pass the cable through the outlet hole 5, pull out the switch body 1, and fix the cable on the top of the corresponding output terminal 13, then install and reset the switch body 1, then twist the rotating handle 8, and the rotating handle 8 drives the control rod 9 to rotate, so as to realize the reversal of the current;

[0042] The control rod 9 includes a reversing rod 19, an insulating ring 20, a metal rod 21 and a metal contact 22. One end of the reversing rod 19 is fixedly connected to the metal rod 21. The insulating ring 20 is fixedly connected to the connection between the metal rod 21 and the reversing rod 19. The outer wall of the metal rod 21 is fixedly connected to the metal contact 22. The metal contacts 22 are provided in several groups and correspond to the output terminals 13.

[0043] The output terminal 13 includes a fastening bolt 23, a metal sheet 24 and a contact copper sheet 25. The fastening bolt 23 is threadedly connected to the metal sheet 24. The metal sheet 24 is fixed to the surface of the sealed housing 10. The bottom end of the fastening bolt 23 is fixedly connected to the contact copper sheet 25.

[0044] When reversing, the metal rod 21 and the metal contact 22 of the control rod 9 are charged, and the turning handle 8 drives the reversing rod 19 to rotate, so that the metal contact 22 contacts the output terminals 13 in different directions, and the output terminals 13 in contact with it are charged. One end of the metal contact 22 is a sharp point and the other end is a smooth design. The contact copper sheet 25 is a three-section bending structure. When the control rod 9 is rotated counterclockwise, the smooth end of the metal contact 22 contacts the contact copper sheet 25, making it charged. When it is rotated clockwise, the tip of the metal contact 22 will be stuck at the corner of the contact copper sheet 25, making it unable to continue to rotate, so that the control rod 9 can only rotate in one direction counterclockwise, and the possibility of misoperation is small.

[0045] A person skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention, including the claims, is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
