Suitable for
Controlling lights from two different points in a hallway or staircase.

Commercial office spaces requiring reliable lighting management.

When it may not be suitable
This switch is not intended for outdoor use or in environments with high humidity, as it carries an IP20 protection rating, meaning it lacks resistance to water and moisture. It is also not suitable for controlling circuits that exceed the 16A or 3520W power capacity limits.

How to use
The Ospel Sonata switch is designed for flush-mounted installation within standard electrical wall boxes.

Once the wires are securely locked in place, mount the switch mechanism into the wall box and attach the decorative frame. Restore power only after the installation is fully secured.
What to consider before purchase
Verify that your existing wall boxes are compatible with the 71 mm x 71 mm dimensions.
Ensure the electrical load of your lighting system does not exceed 3520W.
Confirm that the installation environment is dry and protected from moisture.
Check if your current wiring setup supports a two-way staircase switching configuration.
