The button is movably hinged to the shell body with an elastic part on the driving rod, and also includes a conductive part inserted on the shell body. The top of the conductive part is provided with a fork, including a first contact pin and a second contact pin extending in the rotation direction of the button, and a gap is formed between the first contact pin and the second contact pin. A conductive wire is connected to the indicator light, and the indicator light is turned on by controlling the conductive wire to abut against the first contact pin or the second contact pin through the button. However, the conductive wire is directly forked through the top of the conductive part. When the conductive wire swings, it is in point-to-point hard contact with the corresponding feeler, which is easy to wear and there is a safety hazard. Summary of the invention

[0003] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a three-speed rocker-shaped switch, in which the conductive part contacts the conductive wire through an elastic conductive sheet. The elastic conductive sheet can be relatively elastically deformed to achieve soft contact when in contact, which can reduce wear and is safer when used.

[0004] The utility model discloses a three-speed rocker switch, comprising a switch seat, a button hingedly arranged on the switch seat, a first pin and second pins arranged on two opposite sides of the first pin are arranged on the switch seat, a conductive seesaw is swingably arranged on the first pin, a top rod for driving the conductive seesaw to swing to communicate with the second pin is arranged at the bottom of the button, the top rod swings synchronously with the button and can be retracted relative to the button, an elastic member for driving the top rod to reset is also arranged on the button, an indicator light is also arranged on the switch seat or the button, one end of the indicator light is connected to the first pin, and the other end is connected to a conductive wire, the conductive wire is arranged on the button and swings synchronously with the first pin, a third pin is arranged on the switch seat below the corresponding conductive wire, and the characteristic is that: the top of the third pin is connected to an elastic conductive sheet, the elastic conductive sheet is spaced apart from the conductive wire, and when the conductive seesaw swings to communicate with the second pin, the conductive wire swings to contact with the elastic conductive sheet.

[0005] By adopting the above technical solution, when in use, the push rod can be driven to swing by pressing the button. While the push rod swings, it will push the conductive seesaw to make it swing, thereby contacting the corresponding second pin, thereby realizing the gear switching. At the same time, the conductive wire will contact the elastic conductive sheet, thereby lighting up the indicator light. When the swing amplitude is too large, the elastic conductive sheet can also deform elastically, thereby achieving a soft contact effect, which is safer to use and can also increase the service life.

[0006] The utility model is further configured as follows: the conductive wire is arranged on the button along the length direction of the conductive seesaw, the elastic conductive sheet includes a contact end in contact with the conductive wire and a connecting end connected to the third pin, a contact plane is arranged on the contact end, a transition section for connecting the two into one is arranged between the connecting end and the contact end, and the transition section is arc-shaped or inclined.

[0007] By adopting the above technical solution, when swinging, it is point-to-surface contact, and the structural layout is reasonable, which can further improve the service life and prevent the elastic conductive sheet and the conductive wire from being damaged.

[0008] The utility model is further configured as follows: the button comprises a button cover and a button seat, the button seat has a built-in cavity, the indicator light is arranged in the cavity, and the button cover is arranged on the cavity.

[0009] By adopting the above technical solution and using a button cover and a button seat that are separately arranged, the indicator light can be easily assembled into the cavity.

[0010] The utility model is further configured as follows: an elastic expansion piece is further provided on the outer side of the switch seat, and an anti-backward tooth is further provided on the top of the elastic expansion piece.

[0011] By adopting the above technical solution, the switch can be prevented from slipping out after installation, and is relatively stable when in use. Moreover, after being expanded by the elastic expansion sheet, it will not slide relatively, making it more stable during assembly.

[0012] A further configuration of the utility model is as follows: a stationary contact is also provided on the second pin, and a moving contact for contacting the stationary contact is provided on the conductive seesaw.

[0013] The above technical solution can facilitate the connection between the conductive seesaw and the second pin.

[0014] A further configuration of the utility model is that a waterproof cover is arranged on the switch seat at a position corresponding to the button.

[0015] By adopting the above technical solution, the switch has a waterproof function and is more practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The utility model discloses a three-speed rocker switch, including a switch base 1, a button 2 hingedly arranged on the switch base 1 (the button 2 is most preferably provided with a hinge shaft, and the switch base 1 is provided with a hinge hole, and the hinge can be hinged by cooperating with the hinge shaft and the hinge hole), the switch base 1 is provided with a first pin 3 and a second pin 4 arranged on two opposite sides of the first pin 3, a conductive seesaw 5 is swingably arranged on the first pin 3 (the conductive seesaw 5 is most preferably V-shaped, which belongs to the prior art and will not be described in detail in this article), a top rod 6 for driving the conductive seesaw 5 to swing to communicate with the second pin 4 is provided at the bottom of the button 2, the top rod 6 swings synchronously with the button 2 and can be retracted relative to the button 2, and an elastic member 7 (elastic member 7) for driving the top rod 6 to reset is also provided on the button 2 The component 7 is most preferably a spring, but it can also be a shrapnel, and the elastic component 7 can also control the extension of the push rod to achieve a positioning effect). The switch base 1 or the button 2 is also provided with an indicator light 9 (it is most preferred that the input end of the indicator light 9 carries a load resistor), one end of the indicator light 9 is connected to the first pin 3, and the other end is connected to a conductive wire 10, the conductive wire 10 is arranged on the button 2 and swings synchronously with it, and a third pin 11 is arranged below the corresponding conductive wire 10 on the switch base 1. In the implementation case of the utility model, the top of the third pin 11 is connected to an elastic conductive sheet 12, and the elastic conductive sheet 12 is spaced apart from the conductive wire 10, and when the conductive seesaw 5 swings to connect with the second pin 4, the conductive wire 10 swings to contact with the elastic conductive sheet 12.

[0026] By adopting the above technical solution, when in use, pressing the button 2 can drive the push rod 6 to swing. While the push rod 6 swings, it will push the conductive seesaw 5 to make it swing, thereby contacting the corresponding second pin 4, thereby realizing the switching of gears. At the same time, the conductive wire 10 will contact the elastic conductive sheet 12, thereby lighting the indicator light 9. The conductive wire 10 is separated from the elastic conductive sheet 12, and the indicator light goes out. When the swing amplitude is too large, the elastic conductive sheet 12 can also be elastically deformed, thereby achieving a soft contact effect, which is safer to use and can also increase the service life.

The contact end 121 and the connecting end 122 are most preferably transitioned by an arc-shaped or inclined transition section 123, which can facilitate relative deformation and avoidance of the contact end 121. A contact plane is arranged on the contact end 121. When swinging, it is a point-to-surface contact. The structural layout is reasonable, which can further improve the service life and prevent the elastic conductive sheet 12 and the conductive wire 10 from being damaged.

[0028] The button 2 includes a button cover 21 and a button seat 22. The button seat 22 has a built-in cavity 13. The indicator light 9 is arranged in the cavity 13. The button cover 21 is covered on the cavity 13. The split-type button cover 21 and button seat 22 can facilitate the assembly of the indicator light 9 into the cavity 13.

[0029] The switch seat 1 is also provided with an elastic expansion piece 14 on the outside, and an anti-backward tooth 141 is also provided on the top of the elastic expansion piece 14, which can prevent the switch from slipping out after installation. If it needs to be pulled out, it can be intervened by an appropriate amount of external force. It is relatively stable when used, and after being tightened by the elastic expansion piece 14, it will not slide relatively, making it more stable during assembly.

[0030] The second pin 4 is also provided with a stationary contact 15 , and the conductive seesaw 5 is provided with a movable contact 16 for contacting the stationary contact 15 , so as to facilitate the conductive seesaw 5 and the second pin 4 to be connected.
