3-Way will have one or two leads hot. And one or two ground. Toggling the swich will make one of the hots into a ground or one of the grounds into a hot The remainging lead is either Load (if ground) or HOT.
If it is a tapped in switch then two will be hot and one "Switched" no ground
If it is a lit switch one will always be hot. one always ground and one switched.
