[0025] See also Figures 1 to 9 A toggle switch includes a switch body 1, the switch body 1 including a toggle assembly 11, a contact assembly 12 connected to the toggle assembly 11, and a shell 13 for fixing the toggle assembly 11 and the contact assembly 12, the contact assembly 12 including a plurality of contact strips 121 connected to the toggle assembly 11, and an insulating shell 124 wrapping the contact strips 121, the contact strips 121 are used for electrical connection, the insulating shell 124 is used for electrical isolation, and the contact assembly 12 is molded by an insert injection molding process. The insert molding process can accurately control the position of the contact strip 121, ensuring the accurate position of the contact strip 121 in the contact assembly 12, which is beneficial to improving the electrical performance and service life of the toggle switch. Furthermore, the insulating shell 124 formed by insert molding can effectively isolate the electrical interference between the contact strips 121, thereby improving the safety and stability of the toggle switch. The insulating shell 124 has the same function as the shell in the prior art, and the contact strip 121 has the same function as the contact terminal in the prior art. When making the insulating shell 124, the contact strip 121 is added to the injection mold, and the contact strip 121 is tightly combined with the insulating shell 124 through insert molding to form the contact assembly 12. This design solves the problem of the prior art that the shell and contact terminal need to be manufactured separately and then manually assembled, optimizes the production process and reduces the situation of defective rework in the manual assembly process, while improving the quality assurance of the toggle switch and effectively improving the manufacturability and reliability of the product.

[0026] Further, see Figures 1 to 9 A toggle switch comprises a contact terminal 1211 at the upper end of a contact strip 121, and a conductive terminal 1212 at the lower end. The contact terminal 1211 is connected to the toggle assembly 11, and the conductive terminal 1212 is electrically connected to the outside. When the toggle assembly 11 moves, the contact state between the toggle assembly 11 and the contact strips 121 can be switched, thereby opening and closing or switching the circuit. The contact terminal 1211 and the conductive terminal 1212 are integrally formed with the contact strip 121, reducing the number of solder joints and joints in the toggle switch, lowering the risk of failure due to poor contact or oxidation, and effectively improving the reliability and service life of the toggle switch.

[0027] Further, see Figures 1 to 9 A toggle switch, the toggle assembly 11 includes a toggle block 111, a plurality of sliding contact clips 112 connected to the toggle block 111, an elastic member 113, and a ball 114. The toggle block 111 is provided with a toggle rod 1111 on one side and a positioning hole 1112 on the other side. The upper side of the toggle block 111 is provided with a slide rail 1114 that abuts against the inner side surface of the housing 13. The elastic member 113 and the ball 114 are arranged in the positioning hole 1112. The lower side of the toggle block 111 is provided with an accommodating cavity 1113 with the same number as the sliding contact clip 112. The sliding contact clip 112 is installed in the accommodating cavity 1113, and the sliding contact clip 112 is connected to the contact terminal 1211. The positioning hole 1112 provides an installation position for the elastic member 113 and the ball 114. The combination of the elastic member 113 and the ball 114 provides a self-resetting mechanism, which can ensure that the toggle switch can return to its original position accurately after being toggled, while enhancing the operational feel and reliability of the toggle switch. Furthermore, the sliding contact clip 112 is installed in the accommodating cavity 1113 and connected to the contact terminal 1211. Through the cooperation of the slide rail 1114 on the toggle block 111 and the inner side surface of the shell 13, the sliding contact clip 112 is smoothly switched between different contact terminals 1211, ensuring the stability and accuracy of the electrical connection. At the same time, the setting of the elastic member 113 and the ball 114 provides the reset force of the toggle block 111, making the gear position feel of the toggle operation more obvious and smooth, effectively improving the use texture of the toggle switch.

[0028] Further, see Figures 1 to 9, a toggle switch, the bottom of the sliding contact clip 112 is provided with a first clip 1121 and a second clip 1122, the first clip 1121 and the second clip 1122 are respectively provided with a first protrusion 11211 and a second protrusion 11221 at the contact points with the contact terminal 1211, the first protrusion 11211 and the second protrusion 11221 are respectively in contact with the contact terminal 1211. The first clip 1121 and the second clip 1122 are respectively connected to the two contact terminals 1211 to connect the circuits of the two terminals 1211, and the first protrusion 11211 and the second protrusion 11221 increase the pressure on the contact surface between the sliding contact clip 112 and the contact terminal 1211, which can ensure the stability of the electrical connection of the toggle switch and maintain good contact even under conditions of slight vibration or impact to prevent signal interruption or unstable power transmission. The first protrusion 11211 and the second protrusion 11221 can adapt to the different thicknesses of the contact terminals 1211, ensuring that a stable electrical connection can be formed between the contact terminals 1211 of different specifications, effectively improving the practicality and stability of the toggle switch.

[0029] Further, see Figures 1 to 9 A toggle switch comprises at least two groups of contact terminals 1211, each group comprising a first contact terminal 12111, a second contact terminal 12112, a third contact terminal 12113, and a fourth contact terminal 12114. The first, second, third, and fourth contact terminals 12111, 12112, 12113, and 12114 are spaced evenly apart. This design, with two groups of contact terminals 1211, allows the toggle switch to support a wider range of circuit configurations, enabling dual-circuit control or complex circuit switching, meeting the needs of diverse application scenarios, such as electronic equipment, automobiles, and industrial control. The design of each group comprising four sub-terminals and having equal distances between each contact terminal 1211 enables multi-position switching, ensuring that the sliding contact clip 112 accurately and securely contacts the target contact terminal 1211 during movement, avoiding poor contact or short circuits caused by positional deviation, and effectively improving the reliability and safety of the toggle switch.

[0030] Further, see Figures 1 to 9, a toggle switch, the cross-section of the contact assembly 12 is an "I" shape, the contact assembly 12 includes an upper platform 122 and a lower platform 123, the side of the upper platform 122 is provided with a card slot 1221, the shell 13 is provided with a matching portion 131 on the lower side, the matching portion 131 includes a card connecting portion 1311 matching the card slot 1221, and a card buckle 1312 connected to the card connecting portion 1311 and buckled with the lower end surface of the upper platform 122. The cross-sectional shape of the contact component 12 is designed to be an "I" shape, which can effectively enhance the mechanical strength of the contact component 12 while saving materials and reducing production costs. The card slot 1221 on the side of the upper plane 122 matches the card connection portion 1311 on the lower side of the shell 13, forming a simple and effective mechanical locking mechanism, ensuring a firm connection between the contact component 12 and the shell 13, avoiding loosening due to vibration or external force, and the buckle 1312 is buckled with the lower end surface of the upper platform 122, further strengthening the connection between the contact component 12 and the shell 13, forming a double locking mechanism. In addition, it simplifies the assembly process, does not require additional fasteners, reduces production costs and assembly difficulty, and effectively improves the practicality and reliability of the toggle switch.

[0031] Further, see Figures 1 to 9, a toggle switch, wherein one side of the housing 13 is provided with a lever hole 132 and the other side is provided with a plurality of limit holes 133, the diameter of the ball 114 is larger than the width of the limit hole 133, and the limit hole 133 abuts against the ball 114. The lever hole 132 is used to guide the movement of the lever 1111. When the user operates the lever 1111, the lever 1111 will slide in the lever hole 132, thereby changing the loading of the lever switch, and the function of the limit hole is to provide a positioning point for the toggle switch. The plurality of limit holes 133 respectively represent different gears of the toggle switch. The number and position of the limit holes 133 determine the number of gears and state selection of the toggle switch. The design of the lever hole 132 allows the lever 1111 to extend out of the housing 13, so that the user can operate the toggle switch. Furthermore, the limit hole 133 abuts against the ball 114, and the ball 114 The diameter is greater than the width of the limiting hole 133, which means that the ball 114 cannot pass through the limiting hole 133, but can roll on the edge of the limiting hole 133. When the lever 1111 moves, the ball 114 rolls along the edge of the limiting hole 133 until it reaches the position of the next limiting hole 133. Such a design can increase the operating feel of the toggle switch, provide clean tactile feedback, and allow the user to perceive the change in the state of the toggle switch. At the same time, it limits the movement of the lever 1111 to a certain extent, ensuring the effective connection between the sliding contact clip 112 and the contact terminal 1211, thereby effectively improving the reliability and stability of the toggle switch.

[0032] Further, see Figures 1 to 9 A toggle switch, wherein the number of the limiting holes 133 is at least three, and the center distance between the two limiting holes 133 located at the two ends is the maximum movable distance of the toggle assembly 11. With this design, the three limiting holes 133 mean that the toggle switch has three gears. Furthermore, the design of the center distance between the limiting holes 133 located at the two ends being the maximum movable distance of the toggle assembly 11 makes the two outer limiting holes 133 the boundaries of the toggle switch travel, ensuring that the toggle assembly 11 can only move within a preset range, effectively preventing damage to the toggle switch or abnormal electrical connections caused by excessive toggle, and effectively improving the safety and reliability of the toggle switch.

[0033] Further, see Figures 1 to 9A toggle switch, wherein the contact strip 121 is made of brass, and the insulating housing 124 is made of PA9T plastic. Brass has excellent electrical conductivity, ensuring efficient transmission of current or signals, and is suitable for various electrical and electronic devices. Brass also has good mechanical strength and wear resistance, capable of withstanding frequent physical contact and friction. It also has good oxidation resistance and corrosion resistance, effectively ensuring the stability and reliability of the toggle switch under long-term use. PA9T plastic has extremely high electrical insulation properties, effectively isolating the contact strip 121 to prevent electrical short circuits or leakage. PA9T plastic also has excellent thermal stability and chemical resistance, enabling the toggle switch to be used in harsh environments, effectively improving the practicality and stability of the toggle switch.

[0034] Further, see Figures 1 to 9 In a toggle switch, the conductive terminals 1212 are disposed on opposite sides of the lower platform 123. This design allows the toggle switch to be connected more directly to an external circuit, reduces the complexity of internal wiring, simplifies the electrical connection structure of the toggle switch, and enhances the stability and mechanical strength of the toggle switch structure.

[0035] Working Principle: The sliding contact clip 112 is installed in the accommodating cavity 1113 and is connected to the contact terminal 1211. When the toggle lever 1111 is moved to the left, the ball 114 falls into the limiting hole 133 on the left side. At this time, it is the first gear position. The first clip 1121 is connected to the first contact terminal 12111, and the second clip 1122 is connected to the third contact terminal 12113, so that the circuits corresponding to the first contact terminal 12111 and the third contact terminal 12113 are connected;

[0036] When the toggle lever 1111 is moved to the middle position, the ball 114 falls into the middle limiting hole 133, which is the second gear position. The first clip 1121 is connected to the second contact terminal 12112, and the second clip 1122 is connected to the third contact terminal 12113, so that the circuits corresponding to the second contact terminal 12112 and the third contact terminal 12113 are connected.

[0037] When the toggle lever 1111 is moved to the right, the ball 114 falls into the limiting hole 133 on the right side. At this time, the third gear is reached. The first clip 1121 is connected to the third contact terminal 12113, and the second clip 1122 is connected to the fourth contact terminal 12114, so that the circuits corresponding to the third contact terminal 12113 and the fourth contact terminal 12114 are connected.
