How to use
Installation should be performed by a qualified electrician to ensure safety and compliance with local electrical codes. Begin by turning off the power supply at the main circuit breaker. Remove the existing switch, connect the phase wires to the appropriate terminals on the KOS KOS66 switch, and secure the unit into the wall box. Once the cover plate is attached and the unit is firmly in place, restore power to test the functionality of the switch.
What to consider before purchase

Ensure the switch type matches your specific wiring configuration
Check if the graphite color matches your existing interior decor and other electrical accessories
