1. Identifying Terminals: Before you begin, locate the connection terminals on your switch. They are usually marked or indicated by colors or symbols to facilitate connection.
2. Red Wire Connection: This wire, called phase, is generally connected to the terminal marked "L" or "P". Insert the stripped end of the red wire into this terminal and tighten securely using the screwdriver.
3. Blue Wire Connection: The blue, or neutral, wire may not be directly connected to the switch in some installations. If this is the case in yours, make sure to connect it correctly in your junction box. However, if your switch requires a neutral connection, insert the blue wire into the appropriate terminal and tighten.
4. Connection of the Green Yellow Wire: If your installation requires earthing, this wire, which ensures safety, must be connected to the earth terminal, often represented by an earth symbol. Connect this wire securely to ensure optimal protection against possible current leakage.

After making these connections, ensure that all wires are securely attached and that no bare wires are exposed. Once everything is verified, you can proceed to the next step of your installation.

Step 3: Setting up and securing the switch

After connecting the wires, the next step is to physically install the switch. This equally crucial step ensures that your switch is securely attached, ensuring safe daily use. Here is how to perform this installation optimally:

1. Positioning the switch: Gently insert the switch into the recessed box previously fixed to the wall. Make sure the wires are well placed inside without being pinched or twisted.
2. Fixing the switch: With your screwdriver, screw the switch to the flush-mounting box using the screws provided. Be sure to attach it evenly to avoid any misalignment or tilting.
3. Stability test: Once the switch is screwed in, check its stability by gently touching it. There should be no play or movement. This ensures that the switch will stay in place even after repeated uses.
4. Installing the Finishing Plate: If your switch comes with a plate or a cover, clip it or screw it to give your installation an aesthetic and clean finish.

By following these steps carefully, you will ensure that the switch is not only functional but also durable and safe for all your future uses.

Step 4: Connecting the Lamps to the Switch

After you have the switch securely installed, it's time to connect your light sources. This step will allow you to control your lamps from the installed switch. The quality and safety of lamp connection are essential for worry-free use. Here's how to do it precisely:

1. Identifying Lamp Cables: Locate the wires coming out of your lighting fixtures. Usually, they follow the same color code: red wire for phase, blue wire for neutral and, if necessary, green-yellow wire for ground.
2. Cable Preparation: If you have not already done so, use your wire strippers to remove approximately 5 cm of insulating sheath from the ends of your lamp wires.
3. Connecting to the Switch: Connect the lamp wires to the corresponding terminals on the switch or junction box according to the wiring diagram you are following. Make sure connections are firm and secure, avoiding any risk of short circuiting.
4. Testing the Connection: Before turning the power back on, make sure that all wires are securely connected and insulated, and that nothing can create a short circuit or electrical overload.

Once you have completed these steps, your installation is almost complete. All that remains is to test the correct functioning of your lamps with the switch. Successful commissioning will guarantee you an optimal and secure lighting experience.

Step 5: Checking and validating the installation

Once all connections have been made, it is imperative to check the reliability and safety of your installation before using it regularly. Careful monitoring is essential to ensure everything is working as intended and to prevent any electrical hazards. Follow these steps for a thorough check:

1. Restoring Power: Before restoring power from the electrical panel, make sure one last time that all connections are well insulated and that no bare wire is in contact with another element. Then, return the circuit breaker or differential to the ON position.
2. Functional Test: Flip the switch to turn the lamps on and off. Observe their behavior: they should turn on and off simultaneously without flashing or delay.
3. Visual Inspection: Take a look at the switch and lamps for any abnormalities such as sparks or suspicious noises. Everything should be quiet and without signs of overheating.

If after these checks, your two lamps work correctly with the switch, congratulations, your installation is a success!

Note: Electrical installations offer many possible configurations such as the “back and forth” system or the integration of a light dimmer.
