How to Wire a Double Switch (with Pictures)

To wire a double switch, you'll need to cut the power, remove the old switch, then feed and connect the wires into the double switch fixture. Though it is not difficult to wire a double switch, careful attention to safety is crucial to prevent injury.

Here is a wiring diagram for a light switch (four way light switch). It is possible that you may encounter a double pole light switch within the home, but these are not very common in a residential setting. These switches have four terminals as well, but the terminals are identified as “line” and “load”.

This shows wiring a light switch when the power comes into the light outlet first. The old method of a 2-wire drop is explained along with the current code requirements of using a 3-wire cable ...

Wiring Diagram for Multiple Switched Outlets. This diagram shows the wiring for multiple switched outlets on one switch.
