How to Replace a 3 Way Switch and the dangers of not calling an Electrical Professional - Continue to page 3

Figure 4.

Step 1
The first and most important step is to turn off the circuit that you will be working on. Find the right breaker in the breaker box and flip it to the "Off" position. If you have a fuse box, find the right fuse and remove it completely from the panel. You can verify that the correct circuit has been turned off if the light controlled by the switch no longer works.
Step 2
The next step is to remove the cover and switch from the box.
Step 3
Verify there is no power in the box. This can be done with a tic tester available at Lowes or Home Depot.
Step 4
This is the step that can cause you a big headache so follow it carefully. Before you disconnect the switch determine which wire is connected to the common terminal on the 3 way switch. (The common terminal is usually copper or brown). Mark this wire with tape. Now disconnect the two traveler wires. The screws they are under are the same color. (Usually silver or brass) You might also have a ground wire connected to your switch. (Usually a green or bare copper wire) If there is a ground disconnect it now. If everything is correct you should have now have 3 or 4 wires hanging out of the box.
Step 5
Take your new 3 way switch and locate the common screw. Now take the wire that you marked with tape and connect to this screw. The next step is to connect your two traveler wires to the other two screws. It does not matter which wire goes to which screw as long as there is only one wire under the screw. If you have a ground wire you should now connect it to the green screw.
Step 6
To be safe you can wrap tape around the switch. Make sure you cover the screws so they don’t short to the box. Put the switch and the plate back in the box. At this point you can turn on the power.
Step 6
Here is a simple test to make sure that your 3 way system is operating properly.
