They work via a motorised folding arm that’s attached to a screen. The arm begins in a folded position, however since it is driven by the engine, it begins to unfold. The arm is put in a way that as it begins to unfold, the screen begins to open. To close a screen, the arm begins to fold back again up into its original position, bringing the home window to a close.

Chain actuators work much like rack and pinion actuators. A chain engages with pinions that have been installed on a drive shaft inside an exterior casing. As the pinions spin, the links of the chain are rotated through the casing at a 90-degree angle. This directs the chain into a rigid, directly form, which is extremely resistant to stress and compression. For an electric windows opener, the chain has been attached to a window. So as the chain is directed right into a straight form, the home window is pushed open. And since it retracts into the casing, the windows closes.
These are usually fitted to side hung windows or doors, because they offer a 90-degree opening. Also, they are called folding arm actuators and may be designed to open inwards, outwards or both methods.
