Description

Technical Field

[0001] This utility model relates to the field of switches, specifically to a mixing console switch. Background Technology

[0002] A mixing console, also known as a sound mixing control panel, amplifies, mixes, distributes, modifies, and processes multiple input signals to produce sound effects before outputting them through a bus. Mixing consoles are essential equipment in modern radio broadcasting, stage sound reinforcement, and audio program production systems for broadcasting and recording programs; a professional sound system often revolves around a mixing console. However, with numerous buttons on a mixing console, the switches are particularly important to ensure optimal mixing results.

[0003] Existing mixing console switches have the following drawbacks: They often use a single-layer spring for conductive contact. During mixing, signals need to be transmitted accurately and quickly. The high resistance of a single-layer spring results in slow transmission speed, affecting the mixing effect. Furthermore, the limited contact area between the single-layer spring and the conductive components makes the contact resistance prone to increase with slight deformation or impurities, leading to unstable electrical connections. Current transmission through the single-layer spring is susceptible to interference, affecting the stability of the mixing console. After prolonged use, the single-layer spring is prone to fatigue and deformation due to frequent pressing, resulting in uneven contact pressure with the conductive components. Additionally, the limited elasticity of the single-layer spring means that when damaged, it may not regain its original elasticity, failing to tightly adhere to the conductive components and causing intermittent contact problems, severely impacting the continuity of mixing operations. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a mixing console switch, which can effectively solve the technical problems of existing switches using a single layer of spring contact for conductive contact, resulting in slow signal transmission, unstable electrical connection and easy poor contact.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a mixing console switch, including a push handle, a top cover, a button, and a housing. The top cover is installed on the top surface of the housing, and the push handle is movably installed on the top cover. The bottom of the push handle extends into the interior of the housing, and the bottom of the push handle is connected to the button. One end of the housing has an upward-opening receiving cavity. The interior of the housing is provided with a first spring and a second spring. The first spring is stacked on top of the second spring. The interior of the housing is provided with a plurality of conductive sheets, which are symmetrically arranged between adjacent conductive sheets. The top of the conductive sheet contacts the bottom of the second spring. The interior of the housing is welded with a conductive plate. The top of the conductive plate contacts the bottom of the second spring. One end of the conductive plate extends outward to form a conductive end. An arc-shaped conductive block is welded to one end of the housing near the conductive sheet. The top of the arc-shaped conductive block contacts the bottom of the second spring.

[0006] Furthermore, a waterproof membrane is provided between the button and the first spring sheet, and the button is sealed to the top cover through the waterproof membrane.

[0007] Furthermore, the bottom of the outer casing is provided with two positioning rods, which are symmetrically arranged between each other, and the bottom of the outer casing is provided with several circular grooves, which are symmetrically arranged between adjacent circular grooves.

[0008] Furthermore, the side of the outer shell extends outward to form a locking part, and the side of the top cover is bent outward to form a connecting plate. The surface of the connecting plate is provided with a slot for snap-fit ​​connection with the locking part. The top cover is fixed to the outer shell by snap-fit ​​connection between the locking part and the slot.

[0009] Furthermore, one end of the connecting plate extends outward to form a fixing plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model's mixing console switch, by setting a first spring and a second spring inside the housing, and stacking the first spring on top of the second spring, combined with the contact between the button and the first spring, and the contact design between the conductive sheet and the conductive plate and the second spring, achieves efficient electrical connection and signal transmission. This not only improves the sensitivity and accuracy of switch operation and ensures stable signal transmission during the mixing process, but also enhances the reliability and durability of conductivity through the contact between the arc-shaped conductive block and the second spring. The stacked design of the first and second springs forms a dual conductive path. When a single layer of springs deforms or has poor contact due to long-term pressing, the other layer of springs can ensure circuit continuity, significantly reducing the risk of switch failure and minimizing the occurrence of poor contact.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The following is combined Figures 1-6 The mixing console switch of this utility model is described in detail below:

[0021] A mixing console switch includes a push handle 4, a top cover 2, a button 3, and a housing 1. The top cover 2 is mounted on the top surface of the housing 1. The push handle 4 is movably mounted on the top cover 2, with its bottom extending into the interior of the housing 1. The bottom of the push handle 4 is connected to the button 3. One end of the housing 1 has an upward-opening receiving cavity 9. Inside the housing 1, a first spring 11 and a second spring 12 are arranged, with the first spring 11 stacked on top of the second spring 12. Inside the housing 1, a plurality of conductive sheets 13 are arranged symmetrically between adjacent conductive sheets 13. The top of the conductive sheet 13 contacts the bottom of the second spring 12. Inside the housing 1, a conductive plate 14 is welded, with its top contacting the bottom of the second spring 12. One end of the conductive plate 14 extends outward to form a conductive end 15. An arc-shaped conductive block 18 is welded to the end of the housing 1 near the conductive sheet 13, with its top contacting the bottom of the second spring 12.

[0022] A waterproof membrane 10 is provided between the button 3 and the first spring 11. The button 3 is sealed to the top cover 2 through the waterproof membrane 10. Two positioning rods 16 are provided at the bottom of the outer shell 1. The two positioning rods 16 are symmetrically arranged. Several circular grooves 17 are provided at the bottom of the outer shell 1. Adjacent circular grooves 17 are symmetrically arranged. The side of the outer shell 1 extends outward to form a locking part 8. The side of the top cover 2 is bent outward to form a connecting plate 5. The surface of the connecting plate 5 is provided with a slot 6 that is snapped into the locking part 8. The top cover 2 is fixed to the outer shell 1 by snapping into the locking part 8 and the slot 6. One end of the connecting plate 5 extends outward to form a fixing plate 7.

[0023] In this embodiment, the waterproof membrane 10, through its microporous structure, blocks contaminants such as moisture, dust, and dirt, while allowing air circulation to balance internal and external air pressure, protecting the components of the mixing console switch. The waterproof membrane 10 provides waterproofing, preventing water ingress into the switch and subsequent short circuits. The symmetrically arranged conductive sheets 13 and arc-shaped conductive blocks 18 form a multi-point contact structure, effectively dispersing the current load and reducing the risk of localized overheating. The top cover 2 and the outer shell 1 are quickly assembled without tools via the engaging part 8 and the slot 6. Compared to traditional screw fixing methods, this improves assembly efficiency and avoids... To prevent quality issues such as screw stripping, the bottom positioning rod 16 ensures the installation accuracy of the switch on the PCB board. The bottom circular groove 17 engages with the corresponding position on the PCB board to prevent installation misalignment. The snap-fit ​​part 8 on the side of the outer shell 1 and the connecting plate 5 and slot 6 on the side of the top cover 2 enable quick snap-fit ​​connection between the outer shell 1 and the top cover 2. This connection method not only simplifies the assembly process and improves production efficiency, but also ensures a tight fit between the top cover 2 and the outer shell 1. The fixing plate 7 at one end of the connecting plate 5 further facilitates the switch to snap into the corresponding position on the PCB board.

[0024] During installation, align the mixer switch with the PCB board and insert the conductive end 15 of the conductive plate 14 into the PCB board to solder the electrodes to the PCB board. Position the switch by inserting the positioning rod 16 into the PCB board and solder it in place. After installation, adjust the push handle 4 by tossing it to press the button 3. The button 3 presses the first spring 11, which in turn presses the second spring 12. The bottom of the second spring 12 presses the conductive sheet 13 and the conductive plate 14, making contact between the first spring 11 and the second spring 12, and between the second spring 12 and the conductive plate 14. This creates a closed loop between the conductive plate 14 and the external PCB board through the conductive end 15, thus turning on the mixer switch.

[0025] The mixing console switch in this embodiment achieves efficient electrical connection and signal transmission by setting a first spring 11 and a second spring 12 inside the housing 1, with the first spring 11 stacked on top of the second spring 12. Combined with the contact between the button 3 and the first spring 11, and the contact between the conductive sheet 13 and the conductive plate 14 and the second spring 12, this design not only improves the sensitivity and accuracy of switch operation and ensures stable signal transmission during mixing, but also enhances the reliability and durability of conductivity through the contact between the arc-shaped conductive block 18 and the second spring 12. The stacked design of the first spring 11 and the second spring 12 forms a dual conductive path. When a single layer of springs deforms or has poor contact due to long-term pressing, the other layer of springs can ensure circuit continuity, significantly reducing the risk of switch failure and minimizing the occurrence of poor contact.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
