The arm is put in a manner that as it starts to unfold, the window begins to open. To close a window, the arm starts to fold back again up into its unique position, bringing the screen to a close.

Chain actuators work similarly to rack and pinion actuators. A chain engages with pinions which have been mounted on a drive shaft in a exterior casing. As the pinions spin, the links of the chain are rotated through the casing at a 90-degree position. This directs the chain into a rigid, directly form, which is highly resistant to tension and compression. For an electric windows opener, the chain has been mounted on a window. In order the chain is certainly directed into a straight form, the windowpane is pushed open up. And since it retracts into the casing, the windowpane closes.
These are usually fitted to side hung windows or doors, because they provide a 90-degree opening. Also, they are called folding arm actuators and can be designed to open inwards, outwards or both ways.
