Description

Technical Field

[0001] The utility model relates to the technical field of brake light switches, in particular to a magnetically controlled brake light switch. Background Art

[0002] When driving a car, the driver will step on the car's brake pads to stop the car according to the road conditions and the destination. When stepping on the car's brake pads, the car's brake pads will also touch the brake light switch, connect the brake light circuit, and make the brake light flash, thereby alerting vehicles and pedestrians of the vehicle's driving conditions.

[0003] At present, the internal structure of the brake light switch uses the magnetic control of the reed switch and the permanent magnet to control the conduction and power-off. It is worth noting that the electronic equipment and structure inside the car are too complicated, and due to the magnetic control characteristics of the reed switch and the permanent magnet, the reed switch and the permanent magnet are easily disturbed by the magnetic field. Although the reed switch itself is not magnetic, it can be affected by the external magnetic field. For example, a strong magnetic field will magnetize the reed, and then affect the magnetism of the ferrous material in the tube, causing the switch components to fail and causing problems such as misoperation. Utility Model Content

[0006] Optionally, the brake push piece and the limiting plate are of the same size and shape, and the brake push piece and the limiting plate will limit the sliding penetration of the brake push rod on the surface of the shell.

[0007] Optionally, a side surface of the brake push pad is provided with an anti-wear surface.

[0010] Optionally, one side surface of the circular abutment plate is abutted and firmly secured against one side surface of the sleeve rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model uses an anti-interference pad and an anti-interference iron ring in coordination. Firstly, the anti-interference pad can preliminarily isolate the reed switch and the permanent magnet inside the shell from interference. Secondly, for the reed switch, the anti-interference iron ring under the iron shielding effect can effectively reduce the influence of the interference magnetic field on the reed of the reed switch, thereby improving the working reliability of the reed switch, thereby ensuring the double anti-interference effect of the brake light switch under magnetic control operation.
