The Language selector module is used if you have translated a lot of pages on a website. Instead of having a static link to a page ("English"), you connect a page to the translated page.
The module is associated with the languages that are set up on the website as selectable for Translations. If a page is translated into another language, links to the languages appear in the language selector. It always displays the language name of the page's language.
