I recently ordered "Your First Railroad Tack Pack" to go with some EZ Track and train that I already had.  This pack came with turnouts.  I am very inexperienced and have never actually connected turnouts before but it didn't appear to be difficult.  I tried to wire them up but I am not getting them to work. 
Here is what I tried to do.  I ran the red terminal wire from the AC connectors of the transformer to the 3 prong input in the middle of the switch.  I then ran the green wire from the turnout to the two-prong connector on the side of the switch.  But nothing happens.  I took a volt meter and checked everything.  I am getting juice from the transformer and juice at the three-prong input of the switch.  But there is nothing at either of the other two outputs of the switch.  If I run the terminal wire to the two-prong connector on the side of the switch then I get juice out the other side of the switch, which is a different kind of two prong connector, but I don't get anything on the 3 prong connector.
So, what am I missing?  I was assuming the 3 prong connector in the middle is an input but is that not correct?
Thanks in advance.
