The rocker 300 is inserted into the swing bracket 200, and the rocker 300 can slide reciprocally along the Z-axis extending direction within a set range, and can control the on/off of the center trigger switch 410 arranged in the Z-axis direction by pressing and releasing. Meanwhile, the rocking bar 300 inserted in the rocking bracket 200 can drive the rocking bracket 200 to rock in any direction on the X-Y plane.
As shown in fig. 2, 6 and 8, the swing bracket 200 may include a second bracket 210 and a third bracket 220. The second bracket 210 is sleeved on the first bracket 110 and extends into the first cavity 111 of the housing 100, the second bracket 210 rotates reciprocally around the X-axis within a set range, the third bracket 220 is sleeved in the second cavity 211 of the second bracket 210, and the third bracket 220 rotates reciprocally around the Y-axis within a set range, wherein a touch pad 223 is disposed at the bottom of the third bracket 220, and when the third bracket 220 is sleeved on the second bracket 210, the touch pad 223 extends into the second cavity 211.
As shown in fig. 1, 2 and 6, three mutually perpendicular directions of the rocker switch structure are respectively denoted as an X-axis, a Y-axis and a Z-axis for convenience of description.

In addition, the shapes of the first bracket 110, the second bracket 210 and the third bracket 220 are not limited, and in one embodiment of the present invention, the shapes of the first bracket 110, the second bracket 210 and the third bracket 220 are rectangular, and in other embodiments, the first bracket 110, the second bracket 210 and the third bracket 220 can be rectangular, because the first bracket is easy to control in the X direction and the Y direction, and the operation damping in other directions is larger, so that the rectangular structure has a mechanism for preventing false touch, and two adjacent switches are not easy to trigger simultaneously.
As shown in fig. 4 and 6, the rocker 300 is disposed in the third bracket 220, a button 310 is disposed at the top of the rocker 300, and the bottom of the rocker 300 is inserted into the third cavity 221 of the third bracket 220 along with the rod body and extends to a position in the housing 100 where the central trigger switch 410 can be triggered. In the third cavity 221, the central axis of the rocker 300 coincides with the intersection point of the central connecting lines of the first boss 222 and the second boss 212. The outer diameter of the rocker 300 is matched with the diameter of the third cavity 221, preferably, the rod body of the rocker 300 is in a crisscross structure, and in the third cavity 211, two lateral edges of the crisscross rod body of the rocker 300 are respectively overlapped with the central connecting line of the first boss 222 and the central connecting line of the 212 of the second boss and are closely matched with the third cavity 221. In an embodiment of the present invention, the bottom of the rocker 300 may be a spherical surface, and the center of the spherical surface and the intersection point of the center connecting lines of the first boss 222 and the second boss 212 are together on the central axis of the rocker 300, so as to ensure that the rocker 300 will not slide along the Z axis direction when the swing bracket 200 is driven to swing in the housing 300 to trigger the four outer layer trigger switches 420, so that the start and stop of the false triggering center trigger switch 410 will cause the vibration and abnormal sound of the center trigger switch 410, so as to avoid the fatigue life of the center trigger switch 410 from being reduced due to false triggering.
As shown in fig. 4 to 6, in an embodiment of the invention, a rod body of the rocker 300 is provided with a buckle 320 protruding from an outer wall of the rocker 300, a sidewall of the third bracket 220 is provided with a slot 224 matched with the buckle 320, and a dimension of the slot 224 in the Z-axis extending direction is larger than a dimension of the buckle 320 in the Z-axis extending direction.

The type of the switch 400 is not limited, and the switch 400 may be a micro switch, an electric rubber switch, or other types of switches.
As shown in fig. 3 and 6, the rocker switch structure can realize the control function of opening and closing the switch 400 in five directions of A, B, C, D in the X-Y plane and the Z-axis extending direction by manipulating the rocker 300 with a finger. When the finger manipulates the rocker 300 to swing along the direction a or B on the X axis, the rocker 300 drives the third bracket 220 to swing around the axis of the first boss 222 on the outer side of the rocker, the contact disc 223 at the bottom of the third bracket 220 applies pressure to the outer layer trigger switch 420 on the corresponding direction a or B of the base 700 to trigger the outer layer trigger switch, and when the external force is withdrawn, the rocker 300 and the swing bracket 200 automatically reset under the action of the spring force of the triggered outer layer trigger switch 420; when the finger controls the rocker 300 to swing along the direction C or D on the Y axis, the rocker 300 drives the third bracket 220 and the second bracket 210 to swing around the axis of the second boss 212 on the second bracket 210, the touch disc 223 at the bottom of the third bracket 220 applies pressure to the outer layer trigger switch 420 on the corresponding direction C or D of the base 700 to trigger the outer layer trigger switch, and when the external force is withdrawn, the rocker 300 and the swing bracket 200 automatically reset under the action of the elasticity of the triggered outer layer trigger switch 420; when the finger manipulates the rocker 300 to slide along the Z-axis extending direction, the rocker 300 can slide along the third cavity 221 toward the center trigger switch 410, and when the rocker slides to the set position, the bottom of the rocker 300 applies pressure to the center trigger switch 410 to trigger the center trigger switch, and when the external force is withdrawn, the rocker 300 automatically resets under the elastic force of the center trigger switch 410.
