If you have the satellite images...
 
The easiest way would be to make your map contain both the normal and the
satellite images as layer groups.  Make neither of them visible in the
legend.  Define the map with the normal layergroup enabled and the satellite
image layer group disabled.  
 
Create a button that calls a PHP script in the script frame.  Make this php
script programmatically check the state of these two layer groups in the
current session, turn off the one that is on and the reverse, and refresh
the map.  
 
The basic workflow is something like (untested, and not guaranteed):
 
 - GetMap from the session
 - GetLayerGroups from the MgMap
 - GetItem from the MgLayerGroupCollection for the satellite group
 - GetVisible and then SetVisible (to the inverse of current value) 
 - repeat last two steps for the normal group
 - output some JS to cause a map refresh
 
There is some example code here to help you along here:

You'll be working with the current session map, rather than creating a new
one.  The existing tasks in the viewer sample should help you figure that
part out.  
 
As far as tying the button (or some other element) to this function, passing
the current session id, etc, someone else will need to help with that; I
don't have a lot of experience there.
