Switch between windows is a special button which can open the same dialog as you see when you press the Alt + Tab shortcut keys together on the keyboard. Using that dialog you can quickly preview all of your open windows (for example, open files, folders, and documents) without having to click the taskbar. It displays your open windows in a table. To switch between windows, you can press Alt + Tab the required amount of times. In Windows 7 and above, the Switch between windows button is gone with the Quick Launch toolbar. It is possible to get that button back again. Here is how.
