    Each 3-way swt has 1 screw that says common.The other 2 screws are for travelers.

    The common screw will have a hot on 1 end and the swt-leg on the other end.It does not matter which screw you place the travelers on.

    Now the other swt w/4 screws is called a 4-way.This is where the travelers from each swt split.You will need to put 1 set of travelers on top 2 screws the other set on bottom 2 not cross the pairs.
