[0034] It should be noted that the material of the stepped metal disk 101, the first-level trigger ring 103, the second-level trigger ring 104 and the third-level trigger ring 105 is conductive metal, such as iron, copper, alloy, etc. The material of the metal ball 102 is conductive metal that can be attracted by a magnet, such as iron, alloy, etc. The diameter of the metal ball 102 is 2.5 to 3.5 mm.
[0035] Furthermore, a zero-order groove 101b is provided in the middle of the top side of the stepped metal disk 101, and the metal ball 102 is placed in the zero-order groove 101b as an initial position. The stepped metal disk 101 is divided into three areas by the trigger ring, and the height of each area increases from the inside to the outside, wherein the cross-section of the zero-order groove 101b is an inverted trapezoid, and the height difference between the zero-order sensing surface and the first-order sensing surface of the stepped metal disk 101 at the zero-order groove 101b is h0, the height difference between the first-order sensing surface and the second-order sensing surface of the stepped metal disk 101 at the first-order trigger ring 103 is h1, and the height difference between the second-order sensing surface and the third-order sensing surface of the stepped metal disk 101 at the second-order trigger ring 104 is h2, wherein the height of h0 is 0.06-0.1mm, and the heights of h1 and h2 are both 0.15-0.25mm.
[0036] It should be noted that the top ends of the primary trigger ring 103 and the secondary trigger ring 104 are both set at an oblique angle, which faces the inner side of the stepped metal disk 101, and the top end of the tertiary trigger ring 105 extends out of the top surface of the stepped metal disk 101;
[0037] Both sides of the bevels at the top of the primary trigger ring 103 and the secondary trigger ring 104 are flush with the stepped metal disk 101;
[0038] Specifically, when the metal ball 102 rolls, the metal ball 102 contacts trigger rings of different levels, so that the trigger rings and the stepped metal disk 101 form a loop, thereby monitoring the swing level;

When the metal ball 102 contacts the tertiary trigger ring 105, a loop is generated. After the loop is formed, power will be consumed to generate a low level, and then the low level is output through the tertiary output terminal 105a to be received by the control chip, generating a tertiary oscillation contact signal, thereby generating trigger signals of different levels.
