3Typical 3-Way Switch Wiring, NM Cable. In the 1st diagram below, a 2-wire NM cable supplies power from the panel to the first switch box. The black (line) wire connects to the common terminal of the first 3-way switch. A 3-wire NM connects the traveler terminals of the first and second 3-way switch together. Traveler wires are interchangeable on each switch.
3The diagrams below show the conventional wiring for 3-way switches. Unfortunately, not all 3-way switches are wired the conventional way. See Alternate 3-Way Switch Wiring Configuration for another way 3-way switches may be wired. If you have any problems with these switches, it may be best to call an electrician.
