When I think about what it means to be a Switch, there are two possibilities that present themselves. The first and perhaps most incorrect in usage is the Grey Switch. These are people that take various aspects of their life and mix them together. At work, they might be a supervisor of dozens of people and therefor take on a Dominant persona. While in the bedroom however, they might be submissive to their lover. To them, taking in the whole of their being like this would make them a Switch because they are not an absolute, they are a shade of grey.
