![]() If no connection is available, then attach the ground wire to the box in a solid way. All grounds are connected, and the ground is connected at the light when possible. It's very important that the ground or bare copper wire is connected to the green screws on the switches. There you have it, 3-way switch wiring simplified. Now with that said, just look at the switch again and look at the circuit. Then the traveler wires are connecting both switches and it does not matter which wire goes to which traveler screw. The black wire going to the load will always connect to the common screw on the 2nd switch in the circuit. By looking at the moving 3-way switch above, the hot (black) wire coming from the power source will always attach to the common screw on the 1st switch in the circuit. The best way to simplify wiring a 3-way switch is this. When wiring a 3-way switch, this image on the left will show how the connections should actually look when all connections are made. An antenna is a straight line with three small lines branching off at its end, much like a real antenna.So the circuit above when explained should give you a good concept on how this 3-way circuit works. A resistor will be represented with a series of squiggles symbolizing the restriction of current flow. For example, a switch will be a break in the line with a line at an angle to the wire, much like a light switch you can flip on and off. ![]() Most symbols used on a wiring diagram look like abstract versions of the real objects they represent. Select Show Dimensions to show the length of your wires or size of your component.Ĭlick here to read SmartDraw's complete tutorial on how to draw circuit diagrams and other electrical diagrams. You can also change the size and shape of your line hops. You'll be able to search for additional symbols and open any relevant libraries.Ĭlick on Set Line Hops in the SmartPanel to show or hide line hops at crossover points. If you need additional symbols, click the arrow next to the visible library to bring up a drop down menu and select More. Once connected, it will remain connected even if you move the wire. Drag a symbol onto the line and it will insert itself and snap into place. If you right click on a line, you can change the line's color or thickness and add or remove arrowheads as necessary. To draw a wire, simply click on the Draw Lines option on the left hand side of the drawing area. Special control handles around each symbol allow you to quickly resize or rotate them as necessary. Customize hundreds of electrical symbols and quickly drop them into your wiring diagram. SmartDraw comes with pre-made wiring diagram templates.
