I have a 2005 R1. My signals, horn, and brakes lights all stopped working at the same time after a ride.?

I checked my fuses they were fine. Checked for loose wires they were fine. I tried to see if connections on the switch upfront at the horn or the turn signal switch section were corroded and they all looked fine. I think it is the handle bar switch which controlls the signals and horn went bad. What can it possibly be? I am thinking of replacing the whole turn signal switch but not sure yet. Ideas?
