[0018] Figure 6 is Figure 5 Cross-sectional view taken along B-B in Specific implementation manner

[0019] See the appendix Figures 1 - 6, a rocker switch disclosed by the present utility model includes a bracket assembly and a switch assembly. The bracket assembly includes an L-shaped mounting plate 11, and the mounting plate 11 includes a bottom plate 111. One side of the bottom plate 111 extends by 90° in a flipped manner to form a mounting side plate 112. The switch assembly includes a dial 21, a moving contact disc 22, a switch shaft 23, and a wire board 24 provided with a plurality of static contacts 241. The switch shaft 23 is configured to be restricted to rotate on the bottom plate 111. The bottom plate 111 is provided with a shaft positioning hole 1111, and the switch shaft 23 passes through the shaft positioning hole 1111. One end of the switch shaft 23 has a limiting structure that abuts against and limits the bottom plate 111. The limiting structure is as in the prior art, where a snap ring is installed at the end of the switch shaft 23 and the snap ring abuts against and limits the bottom plate. In this specific embodiment, a limiting end 232 is formed at one end of the shaft rod 231 of the switch shaft 23, and the limiting end 232 abuts against and limits the bottom plate 111. The dial 21 is fixedly sleeved on the switch shaft 23, and a rocker 211 extends radially on the dial 21. A gear position positioning structure is provided between the dial 21 and the bottom plate 111. In this way, the switch shaft 23 is restricted on the bottom plate 111 through the cooperation of the limiting structure and the gear position positioning structure on the dial 21. A support member 12 is provided on the bottom plate 111, and the wire board 24 is fixed on the support member 12 to be erected on the bottom plate 111. The moving contact disc 22 is arranged at a corresponding position of the wire board 24 and cooperates with the static contact 241 correspondingly. The moving contact disc 22 is sleeved on the switch shaft 23 and rotates with the switch shaft 23. The support member 12 includes a rivet 121 and a support sleeve 122. The rivet 121 is inserted into the support sleeve 122, and the support sleeve 122 supports on the bottom plate 111. The wire board 24 is supported on the support sleeve 122 and is riveted on the support member 12 through the riveting end 1211 of the rivet 121. The dial 21 and the wire board 24 are arranged on the side of the bottom plate 111 that bulges towards the mounting side plate 112. An avoidance groove 1121 is provided on the mounting side plate 112, and the avoidance groove 1121 extends along the direction corresponding to the swinging direction of the rocker 211. The rocker 211 of the dial 21 passes through the avoidance groove 1121; in this way, the rocker can swing in the avoidance groove.

[0020] Further, both ends of the avoidance groove 1121 corresponding to the swinging direction of the rocker 211 have limiting end walls 11211 that stop the rocker 211. The rocker 211 is stopped by the two limiting end walls 11211 to constitute the limitation of the extreme positions of the rocker 211. Under this design, the rocker is limited through the avoidance groove. Those skilled in the art can control the position of the limiting end wall as needed to make the extreme position of the rocker correspond to the edge gear position of the switch assembly, so as to prevent the rocker from cutting out the working position of the switch assembly, thereby ensuring the reliable operation of the switch.

[0021] To improve the gear feeling of the rocker switch, the gear structure is further optimized as follows: The gear positioning structure includes a disc-shaped elastic piece 212, a gear bead 213, and a gear slot 1112. A plurality of gear slots 1112 are provided on the base plate 111 and distributed along the rotation direction of the dial 21. A plurality of convex points are formed by stamping on the base plate 111, and a gear slot 1112 is formed between adjacent two convex points. A gear bead receiving hole 214 is provided through the dial 21. The disc-shaped elastic piece 212 is riveted and fixed (fixed to the disc-shaped elastic piece 212 by the riveting nail 2121 shown in the figure) on the dial 21 and covers one end port of the gear bead receiving hole 214 away from the base plate 111. The gear bead 213 is positioned in the gear bead receiving hole 214, and the gear bead 213 extends out through one end port of the gear bead receiving hole 214 facing the base plate 111 and cooperates with the gear slot 1112 correspondingly. The part of the gear bead 213 corresponding to the other port of the gear bead receiving hole 214 abuts against the disc-shaped elastic piece 212. The design of the disc-shaped elastic disc riveted on the dial 21 not only has a compact structure, but also can provide a stronger elastic pressing force for the gear bead 213, so that a greater force is required for the gear bead to jump out of the gear slot, making the gear feeling stronger.

[0022] To make the assembly between the switch shaft and the base plate 111 more compact and reliable, the following design is preferably adopted. The switch shaft 23 includes a shaft rod 231 and a limiting end 232 formed at one end of the shaft rod 231. A shaft positioning hole 1111 is provided on the base plate 111. The shaft rod 231 passes through the shaft positioning hole 1111 and is rotationally and movably fitted in the shaft positioning hole 1111. The limiting end 232 of the switch shaft 23 abuts against the outer side wall of the base plate 111. The shaft rod 231 is in the shape of a stepped shaft, and the shaft rod 231 has a socket shaft section 2311 for the dial 21 to be sleeved. The dial 21 is fixedly sleeved on the socket shaft section 2311, and the disc-shaped elastic piece 212 on the dial 21 presses the gear bead 213 against the base plate 111. The limiting end is used for limiting. After the dial is press-fitted onto the switch shaft, the switch shaft can be restricted on the base plate. Under this design, the cooperation between the gear bead and the gear slot can be further made more compact.

[0023] Furthermore, the static contact 241 is riveted and fixed on the wire board 24 to make it convenient and reliable to fix the static contact to the wire board. A contact seat 25 is provided on the wire board 24. The contact seat 25 is provided with a connecting shaft hole 251 for the switch shaft 23 to pass through and constituting the linkage between the contact seat 25 and the switch shaft 23. The contact seat 25 includes a limiting disc 252 and a mounting boss 253 protruding on the limiting disc 252. The moving contact disc 22 is riveted and fixed on the mounting boss 253. An assembly interval 254 is formed between the moving contact disc 22 and the limiting disc 252. Mounting holes are provided on the wire board 24. The mounting boss 253 passes through the mounting holes, and the edge 241 of the mounting hole of the wire board 24 is inserted into the assembly interval 254. Under this design, the moving contact disc is associated with the wire board, which is convenient for the assembly operation of the rocker switch.

[0024] The rocker switch of the present utility model has the following advantages: 1. The wire board is riveted and fixed on the bottom plate. Compared with the traditional wire board installed with bolts and nuts, the assembly of the switch component is more compact. More importantly, the switch component can be assembled inside the bottom plate (the side where the bottom plate extends by flipping towards the mounting side plate), making the overall structure of the rocker switch more compact. 2. After the switch component is assembled inside the bottom plate, the mounting side plate can be used to limit the rocker. Specifically, through the two limiting end walls of the avoidance groove on the mounting side plate, the position of the rocker can be determined more accurately and reliably. That is, those skilled in the art can control the position of the limiting end wall to ensure that the swinging position of the rocker is consistent with the working gear position of the switch component, so as to ensure the reliable operation of the switch. 3. The gear structure between the dial and the bottom plate is realized by a riveted disc-shaped elastic sheet cooperating with a gear bead and a gear groove on the bottom plate, which has a better sense of gear.
