The wiper relay plays an important role in FAW Jiefang trucks in current control, amplification and protection. It is the bridge between the driver and the wiper system, ensuring that the driver can have a clear and safe driving vision regardless of the weather. Therefore, for FAW Jiefang trucks, the performance and quality of its wiper relay are crucial.

The main function of the wiper relay is to amplify and manage the current of the wiper motor. When the wiper motor needs a large current to work properly, the relay plays a role of current amplification. This design is to protect the circuit and motor from damage caused by excessive current. There is an electromagnetic switch inside the relay. When the current arrives, this switch will act quickly to connect the circuit so that the wiper motor can get the required current to start working.

In addition, the wiper relay also has the function of fault protection. If the wiper motor or circuit has an abnormal condition, such as overload or short circuit, the relay will automatically disconnect the circuit to prevent further damage. This not only protects the wiper system, but also ensures the safety of other electrical components of the vehicle.
