Three Way Switch Diagram One Light. Light switch at one end lights in the middle light switch at the other end and its simple. In a four way switch configuration three switches control a single fixture whether it is a light receptacle or other appliance.
With a pair of 3 way switches either switch can make or break the connection that completes the circuit to the light. In the 1st diagram below a 2 wire nm cable supplies power from the panel to the first switch box. The configuration is called four way because the middle switch in the circuit has four connecting terminals rather than the usual three found on most switches.
Wiring diagram 3 way switch with light at the end in this diagram the electrical source is at the first switch and the light is located at the end of the circuit.
Wiring diagram 3 way switch with light at the end. Wiring diagram 3 way switch with light at the end in this diagram the electrical source is at the first switch and the light is located at the end of the circuit. In this diagram the incoming hot wire attaches to the first switch s common dark colored terminal. Take a closer look at a 3 way switch wiring diagram.
