Finally, once the wiring is in place, you can test the switch by throwing all three switches on and off to ensure the light is functioning as expected. With these simple tips and steps, even an inexperienced DIYer can get to grips with wiring a four way light switch. Just remember to always follow manufacturer’s instructions and use the correct safety equipment when working with electrical components.
