Carmine,
It won't help you if I do it for you, so I'll give you a hint.
I would connect one side of all of the switches together and connect this side to the input of a Decade Counter.
The other side of the switches would be connected to the decoded outputs of a Modulo 12 counter so that it applies a pulse to each of the switches in turn. The Decade Counter will only increment if the respective switch is closed.
If you design a circuit and post it in this forum, we can comment on any short comings.
