Replacing switches in a 4 gang box. Two of them are three way switches. One is wired with the hot and neutral on one side of the switch with the traveller (red)wire on the other side. The other three way switch has the hot wire and traveller on the same side with the white wire( neutral) on the other side. Maybe it has to do with that light circuit has three switches controlling the lights. Can someone set me straight please? Also, there is one switch in the box that I haven’t a clue on what it controls. It’s definitely hot but it’s a mystery.
