Black wire = power or hot wire white wire = neutral bare copper = ground when wiring a 2-way switch circuit, all we want to do is to control the black wire (hot wire) to turn on and off the load this simple diagram below will give you a better understanding of what this circuit is accomplishing. Wiring diagram of switch. In this updated diagram, 3-wire cable runs between the receptacle and switch and the red cable wire is used to carry the hot source to the switch the neutral from the source is spliced through to the switch box using the white wire and in this diagram, the white wire is capped with a wire nut.

More 4-way switch wiring diagrams four-way switch wiring schematic below is another method for wiring 4-way switches the electrical switch box that contains the line and load wires may need to be bigger than the other switch boxes, especially if there are other wires going into the switch box. Wiring of 3-way light switches is certainly more complicated than that of the more common single-pole switch, but you can figure it out if you follow our 3-way switch wiring diagram. with a pair of 3-way switches, either switch can make or break the connection that completes the circuit to the light.. Here's a wiring method that eliminates extra connections and creates a neater installation. instead of running a separate pigtail from the hot wire to each switch, just leave the hot wire extra long. to connect the switches, simply score the wire with your wire stripper and push the insulation to expose about 3/4 in. of bare wire..
