Schémas pour brancher un va-et-vient avec 2 interrupteurs?

Introduction

This tutorial explains how to wire a two-way switch system, also known as a "va-et-vient," using two switches. This setup allows you to control a single light fixture from two different locations, making it ideal for hallways or large rooms. Understanding this wiring technique is essential for anyone looking to improve their electrical skills or undertake home renovations.

Step 1: Gather the Necessary Materials

Before starting the wiring process, ensure you have all the required materials:

• Two two-way switches (interrupteurs va-et-vient)
• Electrical wire (3-core cable recommended)
• Wire strippers
• Screwdriver
• Electrical tape
• Voltage tester

Step 2: Turn Off the Power

Safety is paramount when working with electricity. Follow these steps to ensure a safe working environment:

1. Locate the circuit breaker for the light fixture you will be working on.
2. Turn off the power supply to that circuit.
3. Use a voltage tester to confirm that the power is off at the light fixture and switches.

Step 3: Understand the Wiring Configuration

Familiarize yourself with the wiring layout for a two-way switch system:

• Each switch has three terminals: two for the traveler wires and one for the common wire.
• The common terminal connects to the power source on one switch and to the light fixture on the other.

Step 4: Wire the First Switch

Follow these steps to wire the first switch:

1. Connect the power source wire (live) to the common terminal of the first switch.
2. Connect two traveler wires to the remaining terminals of the first switch. These will run to the second switch.

Step 5: Wire the Second Switch

Next, wire the second switch:

1. Connect the two traveler wires from the first switch to the corresponding terminals on the second switch.
2. Connect the common terminal of the second switch to the light fixture.

Step 6: Connect the Light Fixture

Complete the circuit by connecting the light fixture:

1. Connect the neutral wire from the power source to the neutral terminal of the light fixture.
2. Ensure all connections are secure and use electrical tape to insulate any exposed wires.

Step 7: Test the Setup

After wiring is complete, it’s essential to test the system:

1. Turn the circuit breaker back on.
2. Test the switches to ensure that the light can be turned on and off from both locations.

Conclusion

You have successfully wired a two-way switch system, allowing you to control a light fixture from two different switches. Always remember to prioritize safety by turning off the power before working on electrical systems. For future projects, consider exploring three-way switch configurations, which expand control to three switches. Happy wiring!
