Looking Good 3 Way Electrical Diagram
The basic 3 way switch wiring diagram this is the most common and the easiest wiring diagram to follow of any of the wiring diagrams for a 3 way switch circuit.
3 way electrical diagram. Electrically a typical 3 way switch is a single pole double throw spdt switch. 3 way switch is a multiway switching or interconnection of two or more electrical switches to control an electrical load from more than one location. The line white neutral wire gets connected to the light fixture.
Electricians call the continuous hot wire the line wire. This wire diagram shows the wiring for source power into the first three way switch then 3 wire cable to the next 3 way light switch and then on to the light or light fixtures. By correctly connecting two of these switches together toggling either switch changes the state of the load from off to on or vice versa.
In this diagram the electrical source is at the first switch and the light is located at the end of the circuit. When you make use of your finger or the actual circuit with your eyes it is easy to mistrace the circuit. The black screw on a 3 way switch diagram is for the continuous hot wire that comes from the circuit panel or for the feed wire that runs up to the light fixture.
The diagram below is based on the video you watched above. 3 way switch diagram 2 above shows the electricity source starting at the fixture. Refer to the above 3 way switch diagram.
The black and red wires between sw1 and sw2 are connected to the traveler terminals. Run new cable romex between the 3 way switches. Regardless of what 3 way switch wiring diagram you re following you ll need to use a 3 wire cable to connect the two 3 way light switches.
The white wire of the cable going to the switch is attached to the black line in the fixture box using a wire nut. A 3 way switch wiring diagram is a simple drawing showing how to connect the wires to each of the four screws on the 3 way switch. The switches may be arranged so that they are in the same orientation for off and contrasting orientations for on.
