The power window switch is a switch used to control the raising and lowering of car windows. It is usually located on the door trim panel and is operated by the driver or passenger. Power window switches usually have three positions: up, down, and center. The up position raises the window, the down position lowers the window, and the center position keeps the window in its current position.
How the power window switch works
The working principle of the power window switch is simple. When the switch is pressed, it sends a signal to the power window motor. After the motor receives the signal, it will start to rotate and drive the window up and down. When the switch is released, the motor stops rotating and the windows stop raising and lowering.
