Still stuck, Any ideas

I am currently trying to make a project which requires multiple switching. Too explain when i hit a switch i want all the other switches to be bypassed,so know signal goes though it. and when i hit another i want all but the one i hit to be bypassed.
Is there any easy way of doing this, or could you tell me any way of doing this. I will be willing to listen and learn.
The idea of the mechanical way of doing it sounds a good idea although, it is floor board, so there need sto be space to get my foot in there without hitting any of the other switches.
Could any one point me in the right direction. Thanks for the help
