I don't know whether this will help you, but I use 3M two sided tape to connect a tab button to my iPhone case so I can use a belt clip with it. It adheres quite nicely and withstands plenty of force.
When I need to remove it to change cases, I can take it off and use another piece to connect the tab button to a different case.
If you think this is what you're looking for, you can Google 3M two sided tape and find a wide array of widths and grades.
Hope that helps!
