Ah, so you need to combine the information of 2 switches to get one LED lighted up.

I would say that calls for a logic element, and in your case I think an AND gate will do the work. 

I suppose the switches work with the support voltage of the switch motor?
So may be easiest way is to built such a gate with from transistors by yourself, so you are not limited to 5V.

Here is an example
