<Li> The 2 - conductors from the mains can enter your multiway setup at any of the switch boxes, or even at the box for the load . The box closest to the mains is typically the one that receives the two conductors from the' mains' . </Li> <Li> A 2 - conductor cable (not including an extra third conductor for the' safety ground') is all that is needed between the box at the load, and the 3 - way switch closest to the load . </Li> <Li> Regardless of which box first receives the hot and neutral from the mains, the "hot" must travel unswitched, from there, to the' common' terminal of the 3 - way switch that is opposite - the - load in the multiway switch - series . </Li> <Li> Similarly, regardless of which box first receives the "neutral" from the' mains', the "neutral" must continue' unswitched' to the load's box and the load's "neutral" connection . </Li>

Can a 3 way switch be used as a 4 way
