How to use

Installation should be performed by a qualified professional in accordance with local electrical regulations. Before beginning, ensure the power supply is disconnected at the main circuit breaker. Strip the electrical wires to the appropriate length and insert them into the automatic terminals on the back of the switch until they are firmly locked in place. Once the wiring is complete, mount the switch mechanism into the wall box and attach the cover plate. Restore power and test the switch to ensure the lighting and backlight function correctly.

What to consider before purchase

• Verify that your existing wiring supports two-way switching configurations.
• Ensure the switch is compatible with your current wall box depth and mounting standards.
• Check if the 10AX rating is sufficient for the total load of your lighting circuit.

Usage recommendations: For optimal performance and safety, avoid exceeding the maximum rated current of 10AX. Regularly inspect the switch for any signs of physical damage or loose connections, and keep the surface clean by wiping it with a dry, soft cloth.
