[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] See Figures 1-8 This utility model provides a filament lever switch, which includes a switch housing 1, a conductive component, a lever 4, and a light-emitting element 6.

[0032] The switch housing 1 serves as a mounting carrier for mounting conductive components and lever 4. The switch housing 1 has an overall cuboid structure and can be placed on a desktop as a switch control terminal.

[0033] The conductive component is installed inside the switch housing 1 for connection with the controlled circuit. It includes a first contact plate 21, a central contact plate 22, and a second contact plate 23 arranged in sequence. A switch rocker 3 is provided on the central contact plate 22. The switch rocker 3 can rotate (swing) left and right, so that the end of the switch rocker 3 can selectively contact the first contact plate 21 or the second contact plate 23 to achieve selective conduction. The structure and wiring of the conductive component are conventional technologies, so they will not be described in detail in this embodiment.

[0034] The lever 4 has a rod-shaped structure. To improve the feel, its sidewalls have a certain slope, forming a conical structure with a large end and a small root. The end is semi-circular. In this application, the lever 4 is made of light-transmitting or light-guiding material. An elastic cap 5 is provided at the lower end of the lever 4. The elastic cap 5 contacts the switch rocker 3. By rotating the lever 4, the switch rocker 3 can be driven to rotate, thereby realizing the on / off (connection or disconnection) of the controlled circuit. The elastic cap 5 includes a spring 51 and a cap body 52, both of which are set in the hole at the lower end of the lever 4. The end of the cap body 52 is semi-circular (spherical) and contacts the switch rocker 3. The spring 51 provides elastic force to make the cap body 52 press tightly against the switch rocker 3 to ensure real-time contact.

[0035] In this application, the lever 4 is made of plastic.

[0036] The light-emitting element 6 is a filament installed inside the lever 4. It can emit light, form a switch indicator, and also has a decorative function. The on / off state of the light-emitting element 6 can change with the on / off state of the controlled circuit (conductive component).

[0037] In the first embodiment, the light-emitting element 6 can be turned on when the controlled circuit is connected and turned off when the controlled circuit is disconnected. That is, when the controlled circuit (conductive component) is connected, the light-emitting element 6 is lit, and when the controlled circuit (conductive component) is disconnected, the light-emitting element 6 is turned off. In other words, the switching state of the light-emitting element 6 is synchronized with the on / off state of the controlled circuit, ensuring that the user can intuitively understand the circuit status. It can intuitively display the circuit status and improve the user experience.

[0038] In the second embodiment, the light-emitting element 6 turns on when the controlled circuit is disconnected and turns off when the controlled circuit is connected. That is, when the controlled circuit (conductive component) is connected, the light-emitting element 6 is off, and when the controlled circuit (conductive component) is disconnected, the light-emitting element 6 is lit. In other words, the switching state of the light-emitting element 6 is opposite to the on / off state of the controlled circuit. This makes it easy to quickly identify the switching state in a dark environment, avoid misoperation, and improve safety.

[0039] To avoid the brightness of the light-emitting element 6 interfering with the user, especially to avoid glare at night or in dim environments, in this embodiment, a frosted layer is provided on the surface of the lever 4. That is, the surface of the lever 4 is frosted. Through the frosting treatment, the light can be effectively scattered, improving the uniformity and softness of the light emission, making the entire lever 4 a soft light-emitting element. This reduces the brightness of the light-emitting element 6, reduces visual stimulation, and at the same time maintains a clear indication effect, resulting in a good display effect.

[0040] In this embodiment, the light-emitting element 6 is a strip-shaped filament, specifically, it can be an LED flexible filament or an LED ceramic filament, and its overall structure is strip (column), which is easy to install.

[0041] Correspondingly, a strip-shaped lamp mounting hole is provided inside the lever 4. The mounting hole is coaxial with the lever 4 and matches the length of the light-emitting element 6, ensuring that the filament is firmly embedded and the light is evenly distributed, further enhancing the indication effect and decorative aesthetics.

[0042] Two hinge shafts 43 are symmetrically arranged on the side wall of the lever 4. The two hinge shafts 43 are coaxially arranged, and their axes are perpendicular to each other and intersect the axis of the lever 4. The lever 4 is rotatably connected through the hinge shafts 43. A wire hole 430 is opened at the end of one of the hinge shafts 43, which is used to allow the wire of the light-emitting element 6 to pass through.

[0043] For ease of processing and assembly, in this application, the lever 4 includes an upper lever body 41 and a lower lever body 42 connected to each other. The upper lever body 41 and the lower lever body 42 are coaxially arranged. A lamp mounting hole is formed in the upper lever body 41. The lamp mounting hole has a circular cross-section and its lower end is open for mounting the light-emitting element 6. At the same time, a semi-hinge shaft I 43a is provided on both sides of the lower end of the upper lever body 41. The cross-section of the semi-hinge shaft I 43a is semi-circular. A pressure cap mounting hole is formed on the lower lever body 42. The pressure cap mounting hole is circular and coaxial with the lamp mounting hole of the upper lever body 41. Its lower end is open for mounting the lower pressure cap. A semi-hinge shaft II 43b is provided on both sides of the upper end of the lower lever body 42. The cross-section of the semi-hinge shaft II 43b is semi-circular. The semi-hinge shaft I 43a and the semi-hinge shaft II 43b are spliced ​​together to form a complete hinge shaft 43.

[0044] To improve assembly accuracy and stability, a positioning structure is provided between the upper rod 41 and the lower rod 42. This positioning structure includes a positioning protrusion 431 and a positioning groove 432, which can be interference-fitted to ensure that the upper rod 41 and the lower rod 42 are tightly connected, thus ensuring assembly accuracy and connection reliability.

[0045] This application also includes a circuit board 2, with the light-emitting element 6 electrically connected to the circuit board 2. The circuit board 2 is rectangular, and a first tab 21, a central tab 22, and a second tab 23 are disposed on the circuit board 2 and electrically connected to the circuit on the circuit board 2. A wiring port 24 is provided on the circuit board 2, which is located at the end of the circuit board 2 and is situated on the side wall of the switch housing 1 for easy wiring. In this embodiment, the wiring port 24 is a Type-C port. The Type-C port can serve as an interface for data transmission and power supply, used to connect to the controlled circuit, simplifying the connection process and improving ease of use.

[0046] A lower mounting base is provided inside the switch housing 1. In this application, the switch housing 1 includes a lower housing 11 and an upper housing 12. The lower mounting base is installed on the lower housing 11. The top surface of the lower mounting base has a mounting groove that accommodates the circuit board 2, thereby positioning the circuit board 2. To improve the installation reliability of the circuit board 2 and prevent it from shifting, several positioning posts are provided on the lower housing 11. Correspondingly, positioning holes corresponding to the positioning posts are provided on the circuit board 2. An upper mounting base 7 is fixed to the lower mounting base by screws. The lower end of the upper mounting base 7 contacts the circuit board 2, thereby fixing the circuit board 2. Three strip-shaped holes are provided on the upper mounting base 7, which respectively allow the first tab 21, the center tab 22, and the second tab 23 on the circuit board 2 to pass through.

[0047] Meanwhile, two support seats 71 are provided on the top surface of the upper mounting seat 7. The lever 4 is rotatably mounted between the two support seats 71 through the hinge shaft of its side wall. Specifically, a U-shaped groove is opened on the top of the support column 71, and the hinge shaft 43 of the lever 4 is installed in the U-shaped groove. At the same time, a hole for the lever to pass through is provided on the upper housing 12, and a pressure block is provided for contacting and positioning the hinge shaft 43.
