[0019] Reference Figures 1-9A toggle switch, comprising a switch cover plate 1, a circuit board 2, a micro switch 3, a toggle mechanism 4 and a limiting mechanism 5. The switch cover plate 1 is arranged outside the toggle switch, and generally uses the shell of an electronic product as the switch cover plate 1. The circuit board 2 arranges the circuit of the electronic product, and electronic components are arranged on the circuit board 2. The micro switch 3 is also arranged on the circuit board 2, and the micro switch 3 controls the on-off of the circuit on the circuit board 2. The switch cover plate 1 is provided with a sliding opening 11, and the toggle mechanism 4 is arranged on the switch cover plate 1 and protrudes from the sliding opening 11, so that the toggle mechanism 4 can be operated from outside the switch cover plate 1. The sliding opening 11 is arranged as an elongated hole, so that the toggle mechanism 4 can be slid to different positions to realize the opening and closing of the micro switch 3, specifically including an open position and a closed position. When the toggle mechanism 4 is slid to the open position on the switch cover plate 1, the micro switch 3 is opened, and when the toggle mechanism 4 is slid to the closed position on the switch cover plate 1, the micro switch 3 is closed, thereby realizing the closing and opening of the toggle switch. The limiting mechanism 5 is arranged on the back of the switch cover plate 1, and the toggle mechanism 4 is limitedly installed on the back of the switch cover plate 1, so as to avoid the toggle mechanism 4 from falling off the switch cover plate 1, and to limit the sliding position of the toggle mechanism 4 on the switch cover plate 1. A first fixed connection mechanism 6 is further arranged between the switch cover plate 1 and the circuit board 2, and the switch cover plate 1 and the circuit board 2 are connected together through the first fixed connection mechanism 6. When the toggle switch is operated outside the switch cover plate 1 (that is, the shell of the electronic product), the circuit board 2 can be prevented from shaking on the switch cover plate 1 or even falling off the switch cover plate 1, thereby ensuring the reliability of the electronic product in which the toggle switch is arranged.
[0020] Referring to Figures 3-6 The first fixed connection mechanism 6 comprises a positioning assembly 61 and a fixing assembly 62. The switch cover plate 1 and the circuit board 2 are positioned and installed together through the positioning assembly 61, so as to realize the accurate installation of the switch cover plate 1 and the circuit board 2. The switch cover plate 1 and the circuit board 2 are fixedly connected through the fixing assembly 62, so as to fixedly connect the switch cover plate 1 and the circuit board 2 together.
[0021] Referring to Figures 3-6The positioning assembly 61 comprises positioning posts 611 and positioning holes 612. The positioning posts 611 and the positioning holes 612 are matched, i.e. the number, position and shape of the positioning posts 611 are consistent with the number, position and shape of the positioning holes 612. When the switch cover plate 1 and the circuit board 2 are assembled, each positioning post 611 can be inserted into the corresponding positioning hole 612, thereby positioning the switch cover plate 1 and the circuit board 2. The positioning posts 611 are arranged on one of the switch cover plate 1 and the circuit board 2, and the positioning holes 612 are arranged on the other one of the switch cover plate 1 and the circuit board 2. In the embodiment, the positioning posts 611 are arranged on the switch cover plate 1, and the positioning holes 612 are arranged on the circuit board 2. In actual production, the positioning posts 611 can also be arranged on the circuit board 2, and the positioning holes 612 can be arranged on the switch cover plate 1.
[0022] Referring to Figures 3-6 The fixing assembly 62 comprises fixing posts 621 and fixing screws. The fixing posts 621 and the fixing screws are screwed together, thereby fixing and connecting the switch cover plate 1 and the circuit board 2 together. The fixing posts 621 are arranged on one of the switch cover plate 1 and the circuit board 2, and the other one of the switch cover plate 1 and the circuit board 2 is provided with through holes 622. The fixing screws pass through the through holes and are screwed with the fixing posts 621. Preferably, the fixing posts 621 are arranged on the switch cover plate 1, and the through holes 622 are arranged on the circuit board 2. In this way, the fixing screws can be hidden at the back of the switch cover plate 1, thereby avoiding affecting the appearance of the front of the switch cover plate 1. In addition, the through holes 622 arranged on the circuit board 2 are easier to set, thereby facilitating the production and assembly of the switch. The positioning assembly 61 and the fixing assembly 62 are preferably staggered. In the embodiment, the switch cover plate 1 and the circuit board 2 have a quadrilateral structure. The positioning posts 611 and the positioning holes 612 are arranged at two opposite corners of the quadrilateral, and the through holes 622 and the fixing posts 621 are arranged at the other two opposite corners of the quadrilateral. For products with different shapes, the positioning assembly 61 and the fixing assembly 62 can be arranged according to the actual shape.
[0023] Referring to Figure 4 and Figure 5The switch cover plate 1 and the limiting mechanism 5 are connected together through a second fixed connecting mechanism 7. The second fixed connecting mechanism 7 comprises mounting columns 71 and mounting holes 72. The mounting columns 71 are arranged on one of the switch cover plate 1 and the limiting mechanism 5, and the mounting holes 72 are arranged on the other one of the switch cover plate 1 and the limiting mechanism 5. The mounting columns 71 are matched with the mounting holes 72, i.e. the shape, size and position of the mounting columns 71 are consistent with the shape, size and position of the mounting holes 72, so that the different mounting columns 71 are respectively fixed in the corresponding mounting holes 72, thereby fixing the switch cover plate 1 and the limiting mechanism 5 together, and further fixing the actuating mechanism 4 on the switch cover plate 1. The number of the mounting columns 71 and the mounting holes 72 can be set according to the needs. In the embodiment, the limiting mechanism 5 has a quadrangular structure, and four groups of mounting columns 71 and mounting holes 72 are arranged on the four corners of the quadrangular structure.
[0024] Referring to Figure 4 and Figure 5 , the mounting columns 71 and the mounting holes 72 can be fixed by bonding, screwing or the like. In the embodiment, the mounting columns 71 and the mounting holes 72 are fixed by hot melting. The mounting columns 71 are plastic parts, so that the mounting columns 71 can be conveniently made by using the plastic structure of the switch cover plate 1. During assembly, the mounting columns 71 are first inserted through the corresponding mounting holes 72, and then the part of the mounting columns 71 inserted through the mounting holes 72 is treated by hot melting to have a structure with a larger cross section than the mounting holes 72, so that the mounting columns 71 and the mounting holes 72 are fixed together by hot melting.
[0025] Referring to Figure 8 and Figure 9 , the actuating mechanism 4 comprises a pushing block 41 and a sliding block 42. The pushing block 41 is slidingly arranged on the switch cover plate 1 and protrudes from the sliding opening 11, so as to facilitate the operator to operate the actuating mechanism 4 outside the switch cover plate 1. The sliding block 42 slidingly drives the micro switch 3 to open or close. The sliding block 42 is provided with a driving protrusion 422. When the sliding block 42 slides, the driving protrusion 422 moves with the sliding block 42 to push the micro switch 3 to open or close. The pushing block 41, the sliding block 42 and the driving protrusion 422 have an integrated structure, which is made by, for example, injection molding.
[0026] Referring to Figure 8 and Figure 9, the limiting mechanism 5 includes a limiting plate 51 and an elastic arm 52, the limiting plate 51 limits the installation of the toggle mechanism 4 on the switch cover plate 1. The elastic arm 52 is arranged on the limiting plate 51, the slider 42 is provided with two clamping holes 421, which are an opening clamping hole and a closing clamping hole, corresponding to the opening position and the closing position of the toggle mechanism 4, the limiting plate 51 is in the opening clamping hole when the toggle mechanism 4 is in the opening position, and the limiting plate 51 is in the closing clamping hole when the toggle mechanism 4 is in the closing position. The limiting arm 52 is preferably provided with a hemispherical clamping block 521, and the clamping hole is a hemispherical hole matched with the clamping block, so that the clamping block 521 is more smooth when clamped into or slid out of the clamping hole 421, and the operation of the toggle mechanism 4 is easier.
[0027] As another embodiment, the limiting mechanism 5 includes a limiting plate 51 and two clamping holes, the limiting plate 51 limits the installation of the toggle mechanism 4 on the switch cover plate 1; the slider 42 is provided with a limiting arm, the elastic arm is clamped into one clamping hole when the slider 42 drives the micro switch 3 to open, and the elastic arm is clamped into another clamping hole when the slider drives the micro switch 3 to close.
[0028] Referring to Figures 1-9 In the assembly of the toggle switch, the toggle mechanism 4 is first installed at the sliding opening 11 of the switch cover plate 1, then the limiting mechanism 5 is fixed on the switch cover plate 1 through the second fixed connection mechanism 7, so that the toggle mechanism 4 is limitedly installed on the switch cover plate 1; the micro switch 3 is installed on the circuit board 2, and then the circuit board 2 and the switch cover plate 1 are connected together through the first fixed connection mechanism 6, thereby completing the assembly of the toggle switch. When the toggle switch is used, the toggle block 41 of the toggle mechanism 4 is manually operated, the driving protrusion 422 on the toggle mechanism 4 drives the micro switch 3 to open when the toggle mechanism 4 slides to the opening position, and the driving protrusion 422 on the toggle mechanism 4 drives the micro switch 3 to close when the toggle mechanism 4 slides to the closing position. During the sliding control of the micro switch 3 by the toggle mechanism 4, the hemispherical clamping block 521 is elastically clamped into different clamping holes 421, which can bring the operator an operating feeling and a sound stimulation, and facilitate the operator to identify whether the toggle switch is opened or closed.
