Translate custom post type and taxonomy slug in URL?

I need help how to translate the custom post type and taxonomy when using multisite and multi-language.
I am using subdirectory a /en /sv etc.

Are using the plugin (Multisite Language Switcher), but can not change the rewrite settings there. So I am guesing I have to change some rewrite?
Or should I translate the post type with translations file, .mo .po?

This is how the post type set up are in functions.php.
Should I do something with the rewrite?

So for example on english webpage url would be:
www.mypage.com/en/products

But for the swedish I want
www.mypage.com/sv/produkter

And other language :
www.mypage.com/xx/product-name-in-this-language

How can I manage to get this result? I have searched and search and can not find the right answer.
