Summary: Fully explained wiring diagrams and photos show how to wire switches including: single switches, 3-way switches, 4-way switches, and dimmer switches.


Diagrams for Wiring Light Switches



Before wiring a light switch please consider the following:
Make sure the circuit power has been turned off, and mark the circuit breaker or fuse to indicate that work is being done.
Make sure the switch is correct for your application. The switch should be rated for the circuit voltage and the amperage. For example: A standard light switch in the USA for a bedroom is typically rated for 120 volts, 15 amps.
Before replacing a light switch, make sure to identify the existing wiring before removing the wires. Make a note describing how the wires are connected to the switch. Create a drawing and mark the wires with electrical tape or masking tape. If possible, take a picture of the wiring inside the switch box, and how the wires are attached to the switch.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
