[0002] As a basic electrical control component, a switch uses a sliding slider to toggle the on / off state of a circuit. Its applications are widespread in the control systems of vehicles such as motorcycles and electric vehicles, as well as in numerous fields including industrial equipment and household appliances. For example, in vehicles, it is used to control functions such as turn signals, headlight high / low beam switching, and fog light switching.

[0003] In these applications, especially in harsh conditions such as motorcycles and electric vehicles that face continuous vibration and impact, the clarity of the switch's position feel, the reliability of circuit contacts, and the durability of its structure are crucial. Currently, the internal structure of most switches on the market has room for optimization. For example, the position positioning mechanism in existing switches usually uses an independent steel ball and spring assembly, which requires a dedicated mounting cavity inside the housing. This structure results in a large number of parts and a cumbersome assembly process, thus restricting production efficiency. Utility Model Content

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0025] The switch structure in this embodiment of the utility model is as follows: Figures 1 to 6As shown, it includes a housing 1, a slider 2, and a stop component 3; the housing 1 has an inner cavity 10, and a stationary contact piece 11 is provided on the inner wall of the housing 1; the slider 2 can slide relative to the housing 1 and its lower end extends into the housing 1, and the upper end of the slider 2 has a push handle 21 extending out of the housing 1; the slider 2 has a mounting cavity 22, and the opposite sides of the mounting cavity 22 are respectively provided with an inlet 23 and an outlet 24; the stop component 3 is inserted into the mounting cavity 22 through the inlet 23 and is close to the outlet 24, and the stop component 3 has a positioning head 31 extending out of the outlet 24; the side wall of the inner cavity 10 is provided with a stop groove 12 that cooperates with the positioning head 31. When switching the switch state, the slider 2 is moved laterally by the push handle 21 to switch. When switching to the corresponding stop, the positioning head 31 slides into the corresponding stop groove 12 to cooperate in positioning the slider 2, thereby To ensure stable switch position, the positioner component 22 is preferably made of one-piece plastic injection molding. A movable contact 4 corresponding to the stationary contact 11 is installed at the mounting inlet 23. The movable contact 4 and the positioner component 3 are connected in the mounting cavity 22 by a reaction spring 5. The reaction spring 5 provides opposite elastic forces to the movable contact 4 and the positioner component 3, so that the movable contact 4 and the stationary contact 11 can be in close contact when the switch is in the on state. At the same time, the positioning head 31 on the positioner component 3 can reliably cooperate with the position groove 12. This utility model integrates the positioner component 3, the reaction spring 5 and the movable contact 4 into the same mounting cavity 22 of the slider 2, and provides elastic force to both the positioner component 3 and the movable contact 4 through the reaction spring 5. This design abandons the traditional independent steel ball-spring assembly, reduces the number of parts, simplifies the internal structure, reduces production costs and improves production efficiency.

[0026] See Figures 4 to 6 As shown, the mounting cavity 22 includes at least two mounting areas 221 arranged side by side and connected to each other. Each mounting area 221 is used to install a moving contact 4 and a reaction spring 5. The protrusion 24 is located at one end of one of the mounting areas 221. The stop member 3 has a spring abutment 32 extending into the other mounting areas 221. The spring abutment 32 is used to connect with the reaction spring 5 of the corresponding mounting area 221. With this structure, in actual use, the moving contact 4 and the reaction spring can be installed in some or all of the mounting areas 221 according to production needs. With the matching shell 1 with the corresponding stationary contact 11 structure, different switching functions can be realized, thereby improving the versatility of the slider 2 component, reducing the number of molds and manufacturing costs required for product series development, and reducing the complexity of component management and inventory preparation in the production process.

[0027] For example, in order to facilitate and reliably install the movable contact piece 4, a buckle 222 is provided on the slider 2 at the position corresponding to the movable contact piece 4, and hooks are provided at both ends of the movable contact piece 4 to form a movable engagement with the buckle. The engagement of the hooks and buckles can prevent the movable contact piece 4 from detaching from the slider 2.

[0028] See Figure 3 and Figure 5 The inner cavity 10 has an opening at its upper end, and a limiting frame 6 is provided at the opening. The slider 2 has a limiting step 25 that cooperates with the limiting frame 6. After the slider 2 is installed into the inner cavity 10, the limiting frame 6 is installed to limit the slider 2 to be mounted on the outer shell 1. The cooperation between the limiting frame 6 and the limiting step 25 prevents the slider 2 from falling off the outer shell 1 and allows the slider 2 to slide left and right, thereby ensuring the stability and durability of the product structure. The connection method between the limiting frame 6 and the outer shell 1 can be flexibly set. For example, it can be fixedly connected to the outer shell 1 by snap-fit, or it can be limited by pressure from above by the pressure frame 8 described below.

[0029] Continue reading Figure 3 and Figure 5 The upper end of the outer shell 1 is provided with a protective rubber sleeve 7, and the protective rubber sleeve 7 is provided with a socket hole 71 for engaging with the push handle 21; the periphery of the protective rubber sleeve 7 is fixedly connected to the outer shell 1; by setting the protective rubber sleeve 7, a flexible seal can be formed at the opening of the outer shell 1, which can effectively prevent dust, water vapor and other pollutants from entering the inside of the switch, improve the sealing performance and dustproof and waterproof level of the switch, ensure stable operation in harsh environments, and extend service life.

[0030] See Figure 3 As shown, the periphery of the protective rubber sleeve 7 is pressed against the upper end of the outer shell 1 by the pressure frame 8 to achieve a fixed connection between the protective rubber sleeve 7 and the outer shell 1. The pressure frame 8 is snapped and fixed to the outer shell 1. The pressure frame 8 provides effective clamping force to the protective rubber sleeve 7, ensuring the reliability of the connection and sealing effect between the protective rubber sleeve 7 and the outer shell 1.

[0031] See Figure 3 The stationary contact 11 is fixed to the housing 1 by injection molding, and only its terminal 111 is exposed on the outer surface of the housing 1. The terminal 111 is used to connect external wires so that the switch is connected to the circuit. By setting the stationary contact 11 to only the stationary contact 11 connected to the external wires to be exposed on the housing 1, and the other parts of the stationary contact 11 not to be exposed on the housing, the protection performance can be improved in practical applications, and dust and water can be prevented from penetrating the housing 1 and contacting the stationary contact 11.

[0032] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this invention.
