The two third position-limiting side walls 100c are opposite to each other and arranged at intervals along the second direction Y, and the two third position-limiting side walls 100c extend along the second direction Y. The first direction X and the second direction Y are orthogonal to each other.

The toggle member 11 is disposed in the accommodating slot 100 of the limiting member 10, and the lower surface of the toggle member 11 is closely attached to the bottom surface of the accommodating slot 100, so that there is no gap between the lower surface of the toggle member 11 and the bottom surface of the accommodating slot 100. The toggle member 11 has a toggle body 111, two first elastic members 112 and two second elastic members 113, the two first elastic members 112 and the two second elastic members 113 are disposed on the side surface of the toggle body 111, the two first elastic members 112 abut against the first position-limiting sidewall 100a, and the two second elastic members 113 abut against the second position-limiting sidewall 100 b. The two first elastic members 112 and the two second elastic members 113 are in interference fit with the limiting member 10, so that a gap is formed between the toggle body 111 and the first limiting sidewall 100a and the second limiting sidewall 100b, respectively. The switch 12 is disposed above the toggle 11 and connected to the toggle 11.

When the switch structure 1 of the present embodiment is used, a user applies an external force to push the toggle member 11, and the toggle member 11 moves in the limiting member 10 along the first direction X, so as to switch the switch 12 to the on state or the off state. The lower surface of the toggle member 11 of the present embodiment is in zero-clearance fit with the bottom surface of the receiving groove 100, and meanwhile, the two first elastic members 112 and the two second elastic members 113 are compressed into the receiving groove 100 through their own elasticity in the moving process of the toggle member 11, so as to prevent the toggle member 11 from being excessively tightly fitted with the limiting member 10, so that the toggle member 11 can smoothly move in the limiting member 10, and the switch structure 1 has a good operation hand feeling, when the toggle member 11 stops moving, the two first elastic members 112 and the two second elastic members 113 are in interference fit with the limiting member 10, so as to reduce the displacement generated in the second direction Y in the moving process of the toggle member 11 in the limiting member 10, avoid the side surface of the toggle member 11 colliding with the limiting member 10, and further reduce the chance of generating abnormal sound in the use process of the switch structure 1.

The connecting block 114 has a connecting groove 1141, and the toggle protrusion 121 of the switch 12 is disposed in the connecting groove 1141, so that the switch 12 is connected to the toggle 11. Please refer to fig. 5, which is a top view of the area a in fig. 1; as shown, the toggle protrusion 121 and the connecting groove 1141 of the present embodiment may be in a clearance fit, that is, a gap is formed between a side surface of the toggle protrusion 121 and a side wall of the connecting groove 1141, that is, a width W2 of the connecting groove 1141 is greater than a width W1 of the toggle protrusion 121. Of course, the width W2 of the connecting groove 1141 may be equal to the width W1 of the toggle protrusion 121, or the width W2 of the connecting groove 1141 may be smaller than the width W1 of the toggle protrusion 121, so that an interference fit is formed between the toggle protrusion 121 and the connecting groove 1141.

When the toggle element 11 moves in the limiting element 10, the limiting protrusion 1111 moves in the limiting notch 101, and the limiting notch 101 limits the moving stroke of the limiting protrusion 1111, so as to limit the moving stroke of the toggle element 11 in the limiting element 10. The bottom surface of the receiving groove 100 of the limiting member 10 has a long slide hole 102, the slide hole 102 extends along the first direction X, the surface of the toggle body 111, which is in close contact with the bottom surface of the receiving groove 100, has a pushing protrusion 1112, when the toggle member 11 is disposed in the receiving groove 100 of the limiting member 10, the pushing protrusion 1112 is located in the slide hole 102, the width of the slide hole 102 is greater than or equal to the width of the pushing protrusion 1112, and the length of the slide hole 102 is greater than the length of the pushing protrusion 1112. When the toggle 11 moves in the limiting member 10, the pushing protrusion 1112 moves in the sliding hole 102. The user can move the pushing protrusion 1112 to drive the moving member 11 to move in the position-limiting member 10.

In an embodiment, the surface of the toggle body 111 of the toggle member 11 clinging to the bottom surface of the receiving cavity 100 further has a recess 1113 (as shown in fig. 4) to reduce the contact area between the toggle body 111 and the bottom surface of the receiving cavity 100, and reduce the friction between the toggle body 111 and the bottom surface of the receiving cavity 100, so that the toggle member 11 can move smoothly in the limiting member 10.
