Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a three-position rocker switch. Background Technology

[0002] In the prior art, Chinese utility model patent application number 2024211811837 discloses a three-position rocker switch, including a switch base and a button hinged to the switch base. The switch base has a first pin and second pins located on opposite sides of the first pin. A conductive rocker is oscillating on the first pin. The bottom of the button has a push rod for driving the conductive rocker to oscillate to communicate with the second pin. The push rod oscillates synchronously with the button and can extend and retract relative to the button. The button also has an elastic element for driving the push rod to reset. The switch base or button also has an indicator light. The indicator light has one end connected to the first pin and the other end connected to a conductive wire. The conductive wire is located on the button and swings synchronously with it. A third pin is located on the switch base below the conductive wire. The key feature is that an elastic conductive sheet is connected to the top of the third pin. The elastic conductive sheet is spaced apart from the conductive wire. When the rocker swings to connect with the second pin, the conductive wire swings to contact the elastic conductive sheet. However, the rocker controls the three swing positions as front, middle, and rear. When the rocker switch is to be turned to the middle position (off), it may be turned to the rear position, which is a drawback. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing a three-position rocker switch. Two independently configured conductive rocker plates control the connection of two independent pins, allowing the off position to be set later, thus reducing the probability of misoperation.

[0004] This utility model discloses a three-position rocker switch, including a switch base and a button hinged on the switch base. The switch base is provided with a first pin, a second pin, and a third pin. The second and third pins are arranged side-by-side behind the first pin. A first conductive rocker and a second conductive rocker are oscillatingly arranged inside the switch base. Both the first and second conductive rockers are electrically connected to the first pin. One end of the first conductive rocker is located above the second pin and can swing to be electrically connected to the second pin. One end of the second conductive rocker is located above the third pin and can swing to be electrically connected to the third pin. The end of the second conductive rocker is higher than the end of the first conductive rocker. A push rod is provided at the bottom of the button to drive the first and second conductive rockers to swing. The push rod swings synchronously with the button and can extend and retract relative to the button. The button is also provided with an elastic reset member to drive the push rod to extend. The bottom of the push rod presses against the first and second conductive rockers.

[0005] A further feature of this invention is that the switch base has a central frame inside, which is made of a non-conductive material. The first and second conductive rockers are both oscillatingly mounted on the central frame, and one end of the first pin extends to be fixedly mounted on the central frame and abuts against the bottom of the first and second conductive rockers.

[0006] A further feature of this invention is that: the second conductive rocker has extension plates on both sides, the bottom of the extension plates is arc-shaped, and the end of the first pin that cooperates with the second conductive rocker extends to the bottom of the extension plate and abuts against the extension plate.

[0007] A further feature of this invention is that a guide groove is provided on the extension plate of the middle frame, the top of the guide groove is open to form an assembly port, and the side wall of the guide groove is spaced apart from the extension plate to form a clearance space.

[0008] A further feature of this invention is that the first pin, the second pin, and the third pin extend out of the switch base, and the extended portions of the first pin, the second pin, and the third pin are arranged in a triangular pattern.

[0009] A further feature of this invention is that an elastic tensioning plate is provided on the outer side of the switch base, and the top of the elastic tensioning plate is provided with anti-backward teeth.

[0010] The beneficial effects of this utility model are as follows: When the button swings to the rear end, the first conductive rocker separates from the second pin, and the second conductive rocker separates from the third pin, which is the first position. Because of the hinge relationship, the button can swing relative to the second pin. When the button swings to the point where the drive rod presses the first and second conductive rockers, because the height of the first conductive rocker is relatively low, the first conductive rocker will first contact the second pin to achieve electrical connection, which is the second position. When the button swings further to make the second conductive rocker contact the third pin to achieve electrical connection, it is the third position. When it is necessary to close, the other end of the button can be pressed to make the drive rod swing in the opposite direction and press the first and second conductive rockers to reset. By controlling the connection of two independent pins through two independently set conductive rockers, the disconnect position can be set later, reducing the probability of misoperation.

Detailed Implementation

[0012] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0013] This utility model discloses a three-position rocker switch, including a switch base 1 and a button 2 hinged to the switch base 1. The switch base 1 is provided with a first pin 3, a second pin 4, and a third pin 5. In this embodiment of the utility model, the second pin 4 and the third pin 5 are arranged side by side behind the first pin 3. A first conductive rocker 6 and a second conductive rocker 7 are oscillatingly disposed inside the switch base 1. Both the first conductive rocker 6 and the second conductive rocker 7 are electrically connected to the first pin 3. One end of the first conductive rocker 6 is located above the second pin 4 and can swing to be electrically connected to the second pin 4. One end of the second conductive rocker 7 is located above the third pin 5 and can swing to be electrically connected to the third pin 5. The end of the second conductive rocker 7 is higher than the first pin 3. The end of a conductive rocker 6 (preferably both adopt a V-shaped design, and the included angle of the first conductive rocker 6 is greater than the included angle of the second conductive rocker 7), and the bottom of the button 2 is provided with a push rod 8 for driving the first conductive rocker 6 and the second conductive rocker 7 to swing (preferably two push rods 8 are provided, and each corresponds to one of the two conductive rockers). The push rod 8 swings synchronously with the button 2 and can extend and retract relative to the button 2 (preferably a guide hole is provided at the bottom of the button 2, and the push rod 8 is slidably disposed in the guide hole). The button 2 is also provided with an elastic reset member 9 for driving the push rod 8 to extend (the elastic reset member 9 is preferably a spring, but it can also be a spring sheet), and the bottom of the push rod 8 is pressed on the top of the first conductive rocker 6 and the second conductive rocker 7.

[0014] Using the above technical solution, when button 2 swings to the rear end, the first conductive rocker 6 separates from the second pin 4, and the second conductive rocker 7 separates from the third pin 5. This is the first position, i.e., the disconnect position. Currently, the disconnect positions on the market are all in the middle position. Because of the hinge relationship, button 2 can swing relative to the second pin. When button 2 swings to the point where the drive rod 8 presses the first conductive rocker 6 and the second conductive rocker 7, because the height of the first conductive rocker 6 is relatively low (this height is the distance between the moving contact on the conductive rocker and the stationary contact on the pin), the first conductive rocker 6 will first contact the second pin 4 to achieve electrical connection, i.e., the second position. When button 2 swings further to make the second conductive rocker 7 contact the third pin 5 to achieve electrical connection, this is the third position. When it is necessary to close, the other end of button 2 can be pressed to make the drive rod 8 swing in the opposite direction and press the first conductive rocker 6 and the second conductive rocker 7 to reset. By controlling the connection of two independent pins through two independently set conductive rockers, the disconnect position can be placed at the rear, reducing the probability of misoperation.

[0015] The switch base 1 has a central frame 10 inside. The central frame 10 is made of non-conductive material. The first conductive rocker 6 and the second conductive rocker 7 are both oscillatingly mounted on the central frame 10. One end of the first pin 3 extends to be fixedly mounted on the central frame 10 and abuts against the bottom of the first conductive rocker 6 and the second conductive rocker 7. The central frame 10 facilitates the installation of the first conductive rocker 6 and the second conductive rocker 7. The central frame 10 is made of non-conductive material, which can prevent direct conduction through the central frame 10.

[0016] The second conductive rocker 7 has extension plates 11 on both sides. The bottom of the extension plates 11 is arc-shaped. The end of the first pin 3 that cooperates with the second conductive rocker 7 extends to the bottom of the extension plate 11 and abuts against the extension plate 11. Because the end of the second conductive rocker 7 is relatively high, the swing angle is relatively large. If a flat surface is used to contact the first pin 3, there will be obstruction and hard collision. By setting it to an arc shape, it is easier to drive the second conductive rocker 7 to swing and reduce obstruction.

[0017] The middle frame 10 has a guide groove 12 on the extension plate 11. The top of the guide groove 12 is open to form an assembly port 13. The side wall of the guide groove 12 is spaced apart from the extension plate 11 to form a clearance space. During installation, the second conductive rocker 7 can be lowered from the assembly port 13 along the guide groove 12, which makes the assembly more convenient. The clearance space also allows the extension plate 11 to swing in an arc shape. This method can also have the effect of limiting the swing end. The first conductive rocker 6 can also be designed with an extension plate and a guide groove. Since the first conductive rocker 6 has a relatively small rotation range, its bottom can be an arc surface or a flat surface. When a flat surface is used, it is preferred to provide a swing space space spaced apart from the first pin 3. After swinging, it can contact the first pin 3. Of course, the guide groove can also be set on the extension plate. In this case, a guide rod can be set on the middle frame 10.

[0018] The first pin 3, the second pin 4, and the third pin 5 extend out of the switch base 1, and the extended parts of the first pin 3, the second pin 4, and the third pin 5 are distributed in a triangular pattern. This method provides a larger spacing, making wiring more convenient and improving stability.

[0019] The switch base 1 is also provided with an elastic tensioning piece 14 on the outside, and the top of the elastic tensioning piece 14 is also provided with an anti-slip tooth 15, which can prevent the switch from slipping out after installation, making it more stable during use. Moreover, after the elastic tensioning piece 14 is tightened, it will not slide relative to the switch, making it more stable during assembly.
