Multisite-Language-Switcher
Complex classes like MslsAdmin often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes. You can also have a look at the cohesion graph to spot any un-connected, or weakly-connected components.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.
While breaking up the class, it is a good idea to analyze how other classes use MslsAdmin, and based on these observations, apply Extract Interface, too.

The break statement is not necessary if it is preceded for example by a return statement:
If you would like to keep this construct to be consistent with other case statements, you can safely mark this issue as a false-positive.
