The metal ball 41 is made of steel, and there is a mounting hole 31 on the copper reed 3 for placing the metal ball 41. The metal ball 41 is inserted into the mounting hole 31 by rotating the lever 4, so that the circuit is energized; a toggle protrusion 42 is provided at one end of the lever 4 outside the switch box 1, which can facilitate the toggle of the lever 4. A soft rubber sleeve 421 is also covered on the outer side of the toggle protrusion 42. The material of the soft rubber sleeve 421 is rubber. The soft rubber sleeve 421 can both isolate static electricity and increase friction to make the lever easier to toggle.

[0033] Reference Figure 1 and Figure 2 A soft rubber pad 5 is installed on the outer side of the positioning groove 11. The soft rubber pad 5 is made of rubber. The soft rubber pad 5 is fixed by inserting a fixing protrusion 52 into the fixing groove 12 set on the outer side of the switch box 1. A sliding hole 51 for the lever 4 to pass through is also provided. A fixing groove 41 is provided at the joint between the lever 4 and the soft rubber pad 5. The soft rubber pad 5 can be installed in the fixing groove 41 to prevent the soft rubber pad 5 from falling off during the movement of the lever 4. In order to ensure that the soft rubber pad 5 can fully cover the gap between the lever 4 and the switch box 1, the soft rubber pad 5 has enough bending margin 53 to cope with the moving lever 4, ensuring that when the lever 4 moves to any position, the soft rubber pad 5 can cover the gap to prevent hair debris from entering the switch box 1.

[0034] Reference Figure 2 and Figure 3 A cover plate 6 is installed on the outside of the soft rubber pad 5 for pressing the soft rubber pad 5. The cover plate 6 has a fixing hole 61 corresponding to the positioning groove 11 for the lever 4 to pass through and move; the cover plate 6 is fixed to the switch box 1 by snapping into the mounting groove on the outside of the switch box 1 with a buckle 62.

[0035] The implementation principle of the embodiment of the present application is:

[0036] A hair clipper switch. Inside the switch box 1, two conductive copper posts 2 are installed. The circuit is powered on by the cooperation of the copper spring pieces 3 installed on the conductive copper posts 2 and the metal balls 41 on the lever 4. The lever 4 is installed on the conductive copper post 2 and can rotate around the conductive copper post 2 to drive the metal ball 41 to snap into the installation hole 31 on the copper spring piece 3. To prevent hair debris from entering the switch box 1 through the gap between the lever 4 and the switch box 1, and to avoid hair debris falling on the metal ball 41 causing poor circuit connection and thus leading to switch failure, a soft rubber pad 5 is installed outside the positioning groove 11 to block the hair debris. On both sides of the soft rubber pad 5, there are embedded protrusions 52, and the switch box 1 is provided with embedded grooves 12 corresponding to the embedded protrusions 52. The soft rubber pad 5 is fixedly installed on the switch box 1 through embedding. At the same time, in order to fully block the gap, the soft rubber pad 5 has a bending allowance 53. When the lever 4 moves, the bending allowance 53 of the soft rubber pad 5 can fill the gap generated by the movement of the lever 4.

[0037] To fix the soft rubber pad 5 more firmly on the switch box 1, a cover plate 6 is installed outside the soft rubber pad 5. The cover plate 6 presses the soft rubber pad 5 to prevent the soft rubber pad 5 from falling off due to the movement of the lever 4. On both sides of the cover plate 6, there are buckles 62, and the buckles 62 can be fixed in the installation grooves 14 provided on the outside of the switch box 1. Using the buckles 62 can facilitate the installation and disassembly of the cover plate 6. On both sides of the cover plate 6, there are magnetic parts 63 to make the cover plate 6 more stable.
