[0026] Please refer to Figs. 1-3 , a switch panel is molded in the insert injection molding:

[0027] I. Structure composition

[0028] Clamping cover 1

[0029] Clamping cover 1 as the basic structural component of switch panel, the outer end face is provided with mounting frame 2. The upper and lower ends of clamping cover 1 are provided with contact through holes 11, and these contact through holes 11 are designed to be important. From the functional point of view, the contact through hole 11 provides accurate contact channel for switch contact, so that the switch contact can smoothly pass through and accurately contact the back of the press plate 3. This contact process is the key link to realize the on-off control of circuit, when the press plate 3 is pressed or lifted, the contact state is changed through the switch contact, thereby controlling the conduction and disconnection of circuit. Clamping cover 1 and mounting frame 2 are integrally injection molded into one, the integrated design not only ensures the stability of the structure, but also reduces the error that may occur in the assembly process. The integrated structure makes there be no connecting gap between clamping cover 1 and mounting frame 2, avoids the impurities such as dust, water vapor into the interior to affect the switch performance, and can bear the external force as a whole when bearing external force, improve the overall strength and durability of switch panel.

[0030] Mounting frame 2

[0031] The mounting frame 2 is installed on the outer end face of the snap-fit ​​cover 1. Both the upper and lower inner frame walls are designed with curved surfaces to accommodate the upward movement of the rocker arm 3. This curved surface design ensures that the rocker arm 3 can move smoothly when pressed or raised without being obstructed by the inner wall of the mounting frame 2. The mounting frame 2 provides an enclosure for the rocker arm 3, ensuring that the upper and lower edges of the rocker arm 3 are within this enclosure. This enclosure protects the rocker arm 3, preventing accidental contact with external objects that could lead to misoperation. It also seals the gap between the rocker arm 3 and the outer end face of the snap-fit ​​cover 1, effectively preventing dust or debris from getting trapped inside, which could ultimately cause the rocker arm 3 to malfunction.

[0032] Press the rocker 3

[0033] The rocker switch 3 is installed inside the mounting frame 2, with mounting shafts 31 abutting at the center of both its left and right ends. The mounting shafts 31 on both sides are correspondingly installed at the center of the left and right side walls inside the snap-fit ​​cover 1. This installation method allows the rocker switch 3 to be tilted up and down around the mounting shafts 31. A fluorescent strip 32 is provided near the upper edge of the front of the rocker switch 3. The presence of the fluorescent strip 32 makes it easier for users to locate the switch in low-light environments.

[0034] II. Manufacturing Method

[0035] Injection molding

[0036] The snap-fit ​​cover 1, mounting frame 2, and rocker arm 3 are all manufactured using in-mold injection molding (IMM). IIM ensures the precision and quality of these components while also improving production efficiency and reducing costs. In the IIM process, a pre-designed mold is prepared, and then the raw materials are injected into it. This manufacturing method results in tighter connections between components and a more robust overall structure. Because it involves one-time injection molding within the mold, there are no gaps or weak points at the joints between components, allowing the switch panel to withstand certain external impacts without easy damage during use. Furthermore, IIM allows for precise control of the shape and size of the components, ensuring optimal fit between the snap-fit ​​cover 1, mounting frame 2, and rocker arm 3, thereby guaranteeing the normal operation of the switch panel.
