switch user custom component

We recently modified our community and I lost my switch user component.  I am the community manager but our board is dictated by what our design team created.  I no longer have access to the switch user feature so I thought it would be cool to add this feature to a custom component.  I have the freemarker code to make this only visable to people in specific roles so normal users wouldn't see it.  What I need to know is A) is there a way to see the default lithium component freemarker code so I can duplicate it, or B) does anybody have the freemarker code to add this to a component? 

Essentially, my goal is to add the 'Switch User' button above the 'Go to My Profile' button.  Any additional thoughts or concerns would also be appreciated.  Thanks!
