Switch near fuse box and dashboard on honda accord 2001?

I got used honda accord 2001 last week and i noticed a small on-off press switch down the steering wheel and near to fuse box. I read manual i didn't find what it does. I pressed it while ignition running it does nothing although it feeling like connected to wiring on back of dashboard when i touch it. I think previous owner added it for some reason.Anybody have some idea? Does it turn my car into optimus prime?
