Help to build a circuit to connect one device with four different electronics device

[avis]

I would like to build a circuit to connect one device with four different electronics device. I have to connect only one device at a time.

For example

Device 1, Device A, Device B, Device C, Device D.
I have to connect Device 1 to Device A or Device 1 to Device B or Device 1 to Device C or Device 1 to Device D.

I don't know where to start..
