A window actuator is a mechanical device used to operate the opening and closing of windows, usually in manual or automatic window systems. Its main function is to transfer power (usually from manual operation or electric/pneumatic drive systems) to the window, thereby realizing the opening, closing, adjustment or ventilation functions of the window. Window actuators generally control the opening angle or position of windows through mechanical lever principles or spiral mechanisms. They are key components for realizing automatic or manual operation of windows, and can improve the control accuracy, ease of use and comfort of windows. They are widely used in residential, commercial, industrial and other fields.
