[0014] Advantages of the present utility model:

[0015] 1. Compared with traditional brake light switches, in order to ensure sufficient reset elasticity, the internal spring of the brake light switch is longer, which makes the length of the brake light switch also longer, making the structure of the brake light switch loose and the volume larger, which may affect the installation in the narrow area of the car. By shortening the spring length and increasing the number of springs, the length of the brake light switch is shortened and the volume is reduced without affecting the elasticity of the brake light switch, facilitating the installation of the brake light switch in the narrow car space;

[0016] 2. During the assembly of the switch, the power connection strip is placed in the limiting groove in the limiting plate, and the power connection terminals are located directly above the power connection holes. Then, the contact block is connected to the bottom of the sliding plate with screws. After the sliding plate is placed inside the lower housing, the fixing buckles are aligned with the fixing windows, and then the upper housing is slid and inserted into the lower housing until the fixing buckles are snapped into the fixing windows. Finally, the switch is installed on one side of the brake pedal, and the brake pedal is used to push the contact block to compress the reset spring, so that the power connection strip is separated from the bending plate. Multiple groups of reset springs are provided and shortened to solve the problem that for most brake light switches, in order to ensure sufficient reset elasticity, the internal spring of the brake light switch is longer, which makes the length of the brake light switch also longer, making the structure of the brake light switch loose and the volume larger, which may affect the installation in the narrow area of the car;

[0017] 3. When the brake pedal is depressed, the brake pedal separates from the contact block, and the return spring releases energy to push the sliding plate to move, causing the energizing strip to contact the power receiving strip and the energizing terminal to be inserted into the energizing hole, preventing poor contact due to unevenness between the energizing strip and the power receiving strip. When the power receiving strip contacts the energizing strip, the circuits connected to the two sets of wiring holes are connected respectively, turning on the brake light.

The fixing grooves 202 facilitate the movement of the fixing buttons 201. A power connection hole 203 is opened above the upper housing 2. The cross-section of the power connection hole 203 is the same as the cross-sectional shape of the power connection strip 4. Through the power connection hole 203, it is convenient for the power connection strip 4 to pass through the upper housing 2 to connect the circuit.

[0026] Please refer to Figures 3-4 , in this embodiment, a wiring hole 401 is opened at the upper end of the power connection strip 4. A bending plate 402 is provided at the bottom end of the power connection strip 4. A power conduction hole 403 is opened on one side of the bending plate 402. It is connected to the brake light circuit through the wiring hole 401. The circuit is connected by using the bending plate 402 to contact the power conduction strip 8. Power connection holes 203 are opened on both sides of the sliding plate 5. A limiting plate 501 is provided at the bottom of the sliding plate 5. A limiting groove 502 is opened at the bottom of the limiting plate 501. The power conduction strip 8 is located inside the limiting groove 502.

The circuit is connected to turn on the brake light.
