The diagrams below show the conventional wiring for 3 way switches. Most common is the single pole switch the type used to control a light fixture from a single locationthe next most common is the three way switch which is commonly used to control a light fixture from two different locations. In this diagram the electrical source is at the first switch and the light is located at the end of the circuit. The black line wire connects to the common terminal of the first 3 way switch. In the 1st diagram below a 2 wire nm cable supplies power from the panel to the first switch box. See alternate 3 way switch wiring configuration for another way 3 way switches may be wired.
2 way switch 3 wire system new harmonised cable colours 2 way switching means having two or more switches in different locations to control one lamp.
