[0024] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0026] Example 1 Figure 1-3As shown, a multi-position push-button switch includes a housing 1, with a first male conductive plate 2 and a second male conductive plate 3 extending out of the housing 1. The housing 1 contains a first connecting conductive plate 4 connected at one end to the first male conductive plate 2, a first electronic component 5 connected at one end to the other end of the first connecting conductive plate 4, a second connecting conductive plate 6 connected at one end to the other end of the first electronic component 5, a first spring conductive plate 7 connected to the first connecting conductive plate 4, and a second spring conductive plate 8 connected to the second connecting conductive plate 6. The housing 1 also contains a first button 9, which extends out of the housing 1 and, upon pressing, pushes the movable end of the first spring conductive plate 7 to contact the second male conductive plate 3, and a second button 10, which, upon pressing, pushes the movable end of the second spring conductive plate 8 to contact the second male conductive plate 3. In actual use, the first male conductive piece 2 and the second male conductive piece 3 are connected to the mains power supply. When the first gear is needed, the first button 9 is pressed. At this time, the first button 9 pushes the movable end of the first spring conductive piece 7 to contact and connect with the second male conductive piece 3. At this time, the first male conductive piece 2, the first connecting conductive piece 4, the first spring conductive piece 7, and the second male conductive piece 3 form a circuit and are energized, realizing the first gear of the product. After the first button 9 is released, the first spring conductive piece 7 drives the first button 9 to reset and separate from the second male conductive piece 3, disconnecting the power connection. When the second gear is needed, the first button 9 is pressed. When the second button 10 is released, the second spring conductive plate 8 pushes the movable end of the second spring conductive plate 8 to contact and connect with the second male conductive plate 3. At this time, the first male conductive plate 2, the first connecting conductive plate 4, the first electronic component 5, the second connecting conductive plate 6, the second spring conductive plate 8 and the second male conductive plate 3 form a circuit and are energized, realizing the second position of the product is energized. After the second button 10 is released, the second spring conductive plate 8 drives the second button 10 to reset and separates from the second male conductive plate 3, disconnecting the electrical connection. There is no need to set the connecting conductive line and the button reset spring in the housing 1, which simplifies the overall structure of the switch and facilitates production and assembly.

[0027] Example 2 Figure 4-6As shown, compared to Embodiment 1, a third gear position is added. The housing 1 also includes a third connecting conductive sheet 14, a third spring conductive sheet 15 connected at one end to the second connecting conductive sheet 6, and a third button 16 that, when pressed, pushes the movable end of the third spring conductive sheet 15 into contact with the third connecting conductive sheet 14. A second electronic component 17 connects the second male conductive sheet 3 and the third connecting conductive sheet 14. When the third gear position is needed, the third button 16 is pressed. At this time, the third button 16 pushes the movable end of the third spring conductive sheet 15 into contact with the third connecting conductive sheet 14, connecting them. At this time, the first male conductive sheet 2, the first connecting conductive sheet 4, the first electronic component 5, the second connecting conductive sheet 6, the third spring conductive sheet 15, the third connecting conductive sheet 14, the second electronic component 17, and the second male conductive sheet 3 form a circuit for power supply, enabling the third gear position of the product to operate. After the third button 16 is released, the third spring conductive sheet 15 drives the third button 16 to reset and disconnects from the second male conductive sheet 3, breaking the electrical connection.

[0028] like Figure 1-6 As shown, the housing 1 contains a movable conductive piece 11, one end of which is connected to the other end of the first male conductive piece 2, and a press detection element 12, one end of which extends out of the housing 1 and, when pressed, pushes the movable conductive piece 11 into contact with the first connecting conductive piece 4. The press detection element 12 is equipped with a reset spring 13 to reset the press detection element 12. Before pressing the first button 9 or the second button 10 to energize the switch, the press detection element 12 needs to be pressed, causing it to push the movable end of the movable conductive piece 11 into contact with the first connecting conductive piece 4, thus connecting the first male conductive piece 2 and the first connecting conductive piece 4. Simultaneously, after releasing the press detection element 12, the reset spring 13 causes the press detection element 12 to reset, separating the movable conductive piece 11 from the first connecting conductive piece 4, thus providing mechanical protection for the switch.

[0029] like Figure 1-6 As shown, the pressing detection element 12 includes a detection element connecting rod 121. The lower end of the connecting rod 121 has a detection element pressing part 122 that presses the conductive sheet 11. The upper end of the connecting rod 121 has a detection element pressing cap 123. A return spring 13 is sleeved on the connecting rod 121, with both ends of the return spring 13 contacting the pressing cap 123 and the outer surface of the housing 1, respectively. When the pressing cap 123 is pressed, it drives the pressing part 122 upward through the connecting rod 121 to press the conductive sheet 11. After the pressing cap 123 is released, the compressed return spring 13 returns to its original position, pushing the pressing cap 123 upward, causing the pressing part 122 to separate from the conductive sheet 11.

[0030] like Figure 7As shown, the first connecting conductive sheet 4 has a first vertical portion 41 and a second vertical portion 42 extending upwards respectively. The first spring conductive sheet 7 includes a spring conductive sheet support portion 71 and a spring conductive sheet arc-shaped elastic portion 72. One end of the spring conductive sheet support portion 71 is connected to the first vertical portion 41 of the connecting conductive sheet, one end of the spring conductive sheet arc-shaped elastic portion 72 is connected to the other end of the spring conductive sheet support portion 71, and the other end of the spring conductive sheet arc-shaped elastic portion 72 is connected to the second vertical portion 42 of the connecting conductive sheet. One end of the first button 9 is located on the spring conductive sheet support portion 71 between the first vertical portion 41 and the second vertical portion 42 of the connecting conductive sheet. The second vertical portion 42 of the connecting conductive sheet has a connecting conductive sheet groove 43 for the spring conductive sheet arc-shaped elastic portion 72 to engage, so that the spring conductive sheet arc-shaped elastic portion 72 acts as a spring, so that the button is reset and separated from the conductive sheet in contact with the conductive sheet to disconnect the power. There is no need to set a reset elastic element inside, simplifying the overall structure.

[0031] In this case, the first electronic component 5 is a resistive electronic component; the second electronic component 17 is a resistive electronic component, and different power output levels are achieved by connecting different combinations of resistors in the power-on circuit.

[0032] like Figure 1-6 As shown, contacts 18 are provided at the movable end of the first spring conductive sheet 7, at the contact position between the second male conductive sheet 3 and the movable end of the first spring conductive sheet 7, at the movable end of the second spring conductive sheet 8, at the contact position between the second male conductive sheet 3 and the movable end of the second spring conductive sheet 8, at the movable end of the third spring conductive sheet 15, and at the contact position between the third connecting conductive sheet 14 and the movable end of the third spring conductive sheet 15; contacts 18 are also provided at the movable end of the moving conductive sheet 11 and at the contact position between the first male conductive sheet 2 and the movable end of the moving conductive sheet 11, so as to facilitate contact and energization between the conductive sheets.

[0033] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
