The main control switch in some models may also have a window lock function to avoid the passenger from operating the window without permission. The master switch is usually marked with an icon or text prompt indicating the window position corresponding to each button. When the main control switch of the car electric window is pressed, the electric signal is generated and the instruction is transmitted to the corresponding bus system. Master switches are usually integrated with the vehicle's electrical system to obtain information related to doors and Windows. A master switch with sensors can detect if a window is blocked.
