Honda Fit brake light switch four wire refers to the brake light switch wiring. The four lines represent the normally closed line (COM), the normally open line (NO), the common line (C) and the indicator line (LED).
When the normally closed line is connected to the common line, the brake light is not on; When the brake pedal is pressed down, the normally closed line is disconnected, the common line is connected to the normally open line, and the brake light is on; The indicator line is connected to the indicator to indicate whether the brake light is on or off. By connecting and disconnecting these four lines, the brake light can be switched on and off when the brake pedal is operated, thus providing braking information to other drivers. In general, the four lines represent the on-off state of the brake light switch and signal transmission.
1. Honda Fit brake light switch four wires represent circuit connections of different functions. 2. Because the brake light switch needs to achieve multiple functions, such as brake light, brake light flashing, brake light off, etc., four wires are needed to connect different circuits. 3. These four wires represent brake light, brake light flashing, brake light off and ground wire respectively. Through different circuit connection methods, the multi-functional operation of brake light switch is realized.
Honda Fit brake light switch four wire refers to the brake light switch wiring. The four lines represent the positive and negative terminals of the brake light, the brake pedal switch and the ground wire. The positive and negative electrodes are used for power supply, the brake pedal switch is used to detect whether the brake pedal is depressed, and the ground wire is used for grounding.
Through the connection of these four wires, the normal operation of the brake light can be realized. When the brake pedal is pressed, the brake light will light up to remind the rear vehicle to pay attention. This four-wire connection is a common brake light switch connection method to ensure the normal operation of the brake light and safe driving.
