How to Turn on the Car Windshield Wiper?

[BeckettLee]

Method to turn on the car windshield wiper: On the left side of the steering wheel, there is a wiper switch, which is a toggle lever. Toggling it to the OFF position turns off the wiper, while toggling to other positions turns it on. Regardless of the vehicle's grade, the equipped wipers will have different oscillation frequency settings. Each oscillation setting has its purpose, allowing you to choose the appropriate wiper setting based on actual conditions and habits. The power source of the wiper comes from an electric motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high, typically using a DC permanent magnet motor. The wiper motor installed on the front windshield is usually integrated with the worm gear mechanical part. The function of the worm gear mechanism is to reduce speed and increase torque, with its output shaft driving a four-bar linkage mechanism that converts continuous rotational motion into left-right oscillating motion.
