[0026] The present invention will be further described below with reference to the accompanying drawings. A fuel-saving switch includes a housing 1 and a knob 2 rotatably mounted on the housing. The housing contains a circuit board 3 and a turntable 4 driven by the knob. A conductive sheet 41 is mounted on the turntable, and the conductive sheet cooperates with the circuit board. The switch also includes a buckle 42 on the turntable or knob, and a slot 21 on the knob or turntable, with the buckle engaging with the slot. When the turntable rotates, the position of the conductive sheet on the circuit board changes, thereby adjusting the speed. This is existing technology and will not be described in detail. This application uses a knob with a buckle or slot for mounting the turntable, resulting in a simple structure, convenient assembly, and a very stable fit that will not fall off. The slot can be located on the knob or turntable according to actual needs; similarly, the corresponding buckle can be located on the rotating shaft or knob.

[0027] In this embodiment, as shown in the figure, the knob is provided with a connecting tube 22, part of which extends into the housing. The slot is provided through the circumferential outer wall of the connecting tube. The housing is provided with a through hole for the connecting tube to pass through, and the connecting tube can also rotate within the through hole. The slot is provided on the circumferential wall of the connecting tube.

[0028] In this embodiment, as shown in the figure, the turntable is provided with an elastic arm 43, and the buckle is located at the tail end of the elastic arm. The elastic arm extends into the connecting tube. After the elastic arm extends into the connecting tube and is in place, the buckle extends into the slot through the elastic force of the elastic arm to achieve assembly, resulting in a stable structure.

[0029] In this embodiment, as shown in the figure, at least two elastic arms are provided. Of course, more can also be provided.

[0030] In this embodiment, as shown in the figure, the turntable is provided with a first ball bearing 44, and the inner wall of the housing is provided with a plurality of gear slots 11. The first ball bearing cooperates with the gear slots. When the gear changes, the ball bearing will move from one gear slot to another, which is more convenient for adjustment.

[0031] In this embodiment, as shown in the figure, the turntable is provided with a recessed groove 45, and a portion of the first ball bearings are rotatably disposed within the recessed groove. An elastic element 49 is provided within the recessed groove, with one end of the elastic element pressing against the bottom of the ball bearings. The bottom of the elastic element is located at the bottom of the recessed groove, and the top supports the first ball bearings, facilitating the movement of the ball bearings from one gear slot to another.

[0032] In this embodiment, as shown in the figure, the elastic element is a spring.

[0033] In this embodiment, as shown in the figure, the turntable is further provided with a second ball bearing 48, and the inner wall of the housing is provided with a raceway 12 that mates with the second ball bearing. The cross-section of the raceway can be arc-shaped or V-shaped. The second ball bearing moves within the raceway, making the overall structure more stable. The mounting structure of the second ball bearing can be the same as that of the first ball bearing, and it is also provided with a groove and a spring.

[0034] In this embodiment, as shown in the figure, the bottom of the turntable is provided with a boss 46, and the conductive sheet is provided with a mounting groove that mates with the boss. Assembly and disassembly are relatively convenient.

[0035] In this embodiment, as shown in the figure, the turntable is provided with a guide block 47, and the connecting pipe is provided with a guide groove 221 that cooperates with the guide block. This facilitates installation and positioning.
