Technical Field
[0001] The utility model relates to the technical field of rear brake light switches, in particular to a rear brake light switch. Background Art
[0002] The rear brake light switch is a key component in a car. Its accurate working state directly affects the on and off functions of the car's brake lights.
[0003] During the use of the rear brake light switch, the driver steps on the car brake pad, thereby touching the rear brake light switch to disconnect and close the circuit. It is worth noting that most rear brake light switches are integrated structures. The long-term touch resistance of the car brake pad to the switch will inevitably cause wear of the contact surface. If the switch touch point is damaged due to wear, it will seriously affect the driver's driving safety. In this case, replacing a new rear brake light switch requires a complete replacement, which is not only not conducive to maintenance by maintenance personnel, but also increases the cost of driving.

The central surface of the rear cover 3 is fixedly installed with a second trigger sensor 18 for contact induction and conduction with the first trigger sensor 12. A reset spring 20 is welded between the limit push rod 11 and the rear cover 3. The second trigger sensor 18 passes through the outside of the rear cover 3 and is fixedly connected to a wire 19. The wire 19 passes through the through hole of the rear cover 3 and is fixedly connected to a second sealing ring 21.
[0026] More specifically, in the present embodiment, when any fault occurs in the internal structure of the rear brake light switch or the equipment needs to be updated, the bolts 4 can be used to conveniently install and remove the corresponding front cover 2 and rear cover 3, avoiding the cumbersome phenomenon of overall replacement or disassembly, thereby reducing the driver's cost of using the rear brake light switch; during driving, the anti-wear pad 9 can provide the brake push plate 8 with a wear-reducing effect, thereby extending the service life of the brake push plate 8, and when the worn brake push plate 8 needs to be replaced, it only needs to be replaced by using the threaded rod 7 in the threaded groove 6 of the brake push rod 5, which is convenient for the driver to use, thereby not only reducing the cost of using the rear brake light switch, but also improving the anti-wear purpose.
[0027] When the driver steps on the brake pad of the car during driving, the brake pad of the car pushes the brake push pad 8 and the brake push rod 5, and the brake push rod 5 drives the first trigger sensor 12 on the limit push rod 11 to approach and contact the second trigger sensor 18 for contact conduction.
