Step 1: Locate the light switch you want to replace. Lot of people change the wrong switch on their first try. You can use your RV light switch wiring diagram if it is not clear which one is the correct switch.

Step 3: Remove RV light switch cover over your current switch and pull it out of its socket. Set aside the cover, which you’ll use later on. 

Step 4: Inspect the wires connected to your old light switch. 

If you have a single-pole switch with only two wires, simply unscrew them from the old switch and attach them to your new switch. But what if you have a three-way or four-way switch? Or a camper van conversion light switch (similar to a simple on/off switch but with a dimming slider)?

Step 5: Unscrew the wires from your old light switch wires and attach them to the new ones according to their colors and labels. Plus, you can always refer to the photo you took. Red and black are your hot wires, white is neutral, and green is for grounding. And you always have the positive and negative labels to help you.

Step 6: Screw them on tightly, then place the new light switch into its socket and replace the cover over it. Turn on your power and test out your new switch!

Note: When selecting a replacement switch, choose a perfect replica of your old switch. It should be of the same make and model number to ensure compatibility. This is because different brands tend to have different labeling on the terminals. Also, be sure to double-check that the new switch is rated for use in an RV (the packaging should say).

When to bring in a professional

Of course, there are always times when it’s best for an electrician to come to change the light switches.
