I am having difficulty on using the language switcher in joomla 3.4.8 followed every step still not working. 

I decided to create manual buttons each button will change to the language in question. 

How can I create the link to change to french or English or any other loaded language?

I am looking for something programatically to load like this in module language switcher: `<a href="<?php echo $language->link;?>">`

Thank you.
