Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This application discloses a power switch. (Refer to...) Figure 1 , Figure 2The power-off switch includes a housing 11, a knob 12, a rotating rod 13, a pin 14, a shaped base 15, a conductive sheet 16, a post 17, a conductive clip 18, a limiting groove 19, a first elastic component 20, a second elastic component 21, and an indicating instrument 22. The top end of the rotating rod 13 extends upward through the top surface of the housing 11. The bottom surface of the knob 12 mates with the top end of the rotating rod 13. The shaped base 15 is located inside the top surface of the housing 11. The lower surface of the shaped base 15 has a cross-shaped abutment groove, and the horizontal groove 151 and the vertical groove 152 of the cross-shaped abutment groove have a height difference H1. The area between the horizontal groove 151 and the vertical groove 152 is curved. The rotating rod 13 is horizontally fitted with a pin 14, and the pin 14 abuts in the abutment groove (or abuts in the horizontal groove). The outer wall of the conductive sheet 16 is slidably connected to the inner wall of the limiting groove 19 (or abutting against the vertical groove 152). The outer wall of the conductive sheet 16 is in contact with the inner wall of the limiting groove 19 and slides. The conductive sheet 16 is located below the rotating rod 13. The column head 17 and the conductive clip 18 are respectively located on the left and right sides of the rotating rod 13 and are both located at the top of the limiting groove 19 and extend into the limiting groove 19 at least partially. The first elastic component 20 and the second elastic component 21 are both springs. The first elastic component 20 and the second elastic component 21 are respectively located on the left and right sides of the rotating rod 13. One end of the first elastic component 20 and the second elastic component 21 are both connected to the inner side of the bottom surface of the outer shell 11, and the other end is both connected to the lower surface of the conductive sheet 16. When the pin 14 abuts against the horizontal groove 151, there is a height difference H3 between the upper surface of the conductive sheet 16 and the lower surface of the post head 17 and the lower surface of the conductive clip 18. When the pin 14 abuts against the vertical groove 152, there is a height difference H2 between the upper surface of the conductive sheet 16 and the lower surface of the rotating rod 13. H1 = H2 + H3. The indicating instrument 22 is disposed in a groove on the surface of the housing 11.

[0016] An embodiment of this application describes a method for implementing a power switch as follows: (Refer to...) Figures 1-2In use, the power-off switch's pin 17 is fitted onto the battery terminals (the attached drawing only shows the part of pin 17 inside the housing 11 that connects and disconnects with the conductive sheet 16; the part of pin 17 that can be fitted onto the battery terminals is not shown, as this part is exposed outside the housing 11). The power-off switch's conductive clip 18 is fitted onto the electrical equipment (the attached drawing only shows the part of conductive clip 18 inside the housing 11 that connects and disconnects with the conductive sheet 16; the part of conductive clip 18 that can be fitted onto the electrical equipment is not shown, as this part is exposed outside the housing 11). When the pin 14 abuts against the vertical groove 152 (recess) of the abutment groove, rotating the knob 12 causes the rotating rod 13 to rotate 90 degrees, and the pin... 14. Then rotate 90 degrees, and the pin 14 rotates from the vertical groove 152 (recess) to the horizontal groove 151 (protrusion). At this time, the rotating rod 13 moves downward. The lower surface of the rotating rod 13 drives the conductive piece 16 to move downward along the limiting groove 19 by a height H3, while disconnecting the conductive piece 16 from the post head 17 and the conductive clip 18. At this time, it is in the de-energized state. Rotate the knob 12 in the opposite direction by 90 degrees, and the pin 14 rotates from the horizontal groove 151 (protrusion) to the vertical groove 152 (recess). At this time, the rotating rod 13 moves upward. Under the elastic force of the first elastic component 20 and the second elastic component 21, the conductive piece moves upward along the limiting groove 19 by a height H3, so that the conductive piece 16 is connected to the post head 17 and the conductive clip 18. At this time, it is in the energized state.

[0017] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
