Light Switch Wiring Diagrams

This is an updated version of the first arrangement. Because the electrical code as of the 2011 NEC update requires a neutral wire in most new switch boxes, a 3-wire cable runs between the light and switch. The red and black are used for hot and the white neutral wire at the switch box allows for powering a timer, remote control, or other programmable switch.

With alternate light switch wiring, an NM cable supplies line voltage from the electrical panel to a light fixture outlet box. Another NM cable connects from the light fixture box to the switch box. In the diagram below right, a 2- wire NM cable that connects the light fixture to the switch carries 2 line wires (one line, and one switched line).

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. Connect the last switch in the usual manner, looping the wire around the screw in a clockwise direction.

Connect the "source" wire to the bottom terminal of the switch and the other black wire to the top terminal. In this picture, you can see the strip gauge on the back of the switch. This gauge is when you want to use the "quick-connect" method when wiring a light switch. Simply strip the wire to the length specified and push the wire into the hole.

Installing additional electrical wiring for light switches should be done according to local and national electrical codes with a permit and be inspected.

The video covers how to wire a basic 15 amp single pole light switch with 14/2 electrical wire. In the tutorial, viewers will see the use of: wire strippers, utility knife, needle-nose pliers, and ...

By wiring a 2-way switch, The circuit below shows the basic concept of electricity flow to the load. Let's assume the load you are controlling is a light. The electricity flows from the hot wire (black) through the 2-way switch (shown in off position) and then to the light and returns through the neutral wire (white).

The wall switch is one of the most common and important electrical devices in the home. There are several different types of switches, and although they may look the same when they are installed with their faceplates intact, the various switches look and function differently on the inside. Most of the common types of switches come in different styles, such as toggle, rocker, slider, or push ...

Wiring a 3-Way Light Switch. Wiring a 3-way light switch 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 can make or break the connection that completes the circuit to the light.
