[0002] With the continuous development of automobile technology, the types of electrical devices used in vehicles are increasing. Among them, the brake light switch plays an increasingly important role. It not only sends a signal to light up the brake light when braking, but also provides signals to other systems, including EMS system, ESC system, TCU system, etc. If the brake light switch signal is abnormal, it will directly lead to many functions of the vehicle being restricted or even lost. Therefore, the accuracy of the brake switch signal is very important, and various car companies have put forward high requirements for the reliability of the brake light switch.

The base is equipped with two sets of moving and static contacts, and the base and the shell are assembled and connected by screws to realize the two sets of moving and static contacts. At this time, there is no guiding effect between the base and the shell. When assembled and connected by screws, the surface of the moving and static contacts installed inside is easily damaged, thereby reducing the service life of the double-contact brake light switch.

[0020] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "front", "back", "inside", "outside", "vertical", "horizontal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore are not to be construed as limiting the present invention. In addition, the terms "first", "second" and "third" are only used for descriptive purposes and are not to be construed as indicating or implying relative importance.

[0022] like Figure 1-4 It is a structural schematic diagram of a double-contact brake light switch of a preferred embodiment of the utility model. In this embodiment, a double-contact brake light switch includes a base 1 and a shell 7. Through an installation cavity 2 opened in the base 1, two sets of moving and static contacts are provided for installation. At the same time, the rear end of the base 1 is located in the installation cavity 2 and is fixedly connected with a fixing seat 3, so as to provide a reset force for the spring. Fixed blocks 4 are fixedly connected near the fixing seats on both sides of the inner wall of the installation cavity 2, and a connecting position 5 is formed between the fixed block 4 and the fixing seat 3, and a connecting block 10 is fixedly connected at a relative position to the connecting position 5 at the bottom of the shell 7. The connecting block 10 moves in the connecting position 5, so that when the shell 7 and the base 1 are spliced, the connecting block 10 is inserted into the connecting position 5, and the corresponding position of the shell 7 and the base 1 can be achieved, thereby effectively solving the problems raised in the background technology.

[0023] In this embodiment, the connection block 10 is matched with the connection position 5. This structural arrangement facilitates the assembly between the housing 7 and the base 1 without resistance.

[0024] In this embodiment, a first connecting hole 6 is opened on the top surface of the fixing seat 3, and an internal thread 61 is opened below the inner wall of the first connecting hole 6. When the connecting block 10 is inserted into the connecting position 5, the shell 7 and the base 1 are assembled and threadedly connected with the internal thread 61 through fasteners, so that the shell 7 and the base 1 are connected and fixed.

[0025] In this embodiment, a second connecting hole 8 is opened on the shell 7 at a position opposite to the first connecting hole 6. A fixing ring 9 is fixedly connected to the second connecting hole 8 through the bottom surface of the shell 7, and the fixing ring 9 is adapted to the first connecting hole 6. The fixing ring 9 is clamped on the upper inner wall of the first connecting hole 6, and the auxiliary connecting block 10 and the connecting position 5 play a role in facilitating guidance.

[0026] In this embodiment, the connection position 5 is designed in a Z-shaped structure. Its design can effectively prevent longitudinal and lateral displacement between the shell 7 and the base 1 when they are assembled without being threadedly connected to the internal thread 61 by fasteners, thereby reducing damage to the moving contacts.

[0027] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
