Do it Yourself - How to wire electrical switches.
Wiring Home > Electrical > Switches and lighting
This section covers basic electrical switching. Switches have differant ratings, some switches may be rated for 15amps at 125 volts, while others will have higher voltage and ampere ratings. Make sure you use the switch that is rated for the voltage and amperes you are using.
It is a good idea to never exceed 80% of the ampere rating of a switch. It is also important not to use cheap switches, you really do get what you pay for when purchasing electrical devices devices and it is too important that they function properly and endure daily usage.
The three sections below will guide you through the wiring of switched circuits. If you are going to replace a switch just go to the section of the type of switch you are going to replace. If you are going to be wiring new switching circuits I would suggest you read all three.
It is important to note that electrical codes change, and that in some areas local electrical codes are not the same as the National Electrical code. The local authority having jurisdiction in your area may have different codes than the national code. It is important to find out if your local codes differ from the national code, your local authority having jurisdiction is the final judge and jury.
