🔧 About the Adapter

The adapter and accompanying parts are designed to house the Shelly BLU Wall Switch PCB and battery within the LK FUGA assembly.

This allows the Shelly switch to be integrated into a standard 1-module LK FUGA frame for a more discreet and seamless look.

🧩 Required Parts

In addition to the 3D-printed parts and the Shelly BLU Wall Switch, you will need:

• 1× LK FUGA technical mounting frame, 1-module

• 1× LK FUGA Design frame, 1-module

• 1× LK FUGA cover plate for low-voltage push-button

• 2× LK IHC Wireless blank rocker buttons

Note: The suggested LK FUGA technical mounting frame and LK FUGA Design frame are examples only. You can choose other compatible LK FUGA mounting frames and design frames depending on your installation and preferred appearance.

🔋 Battery

The design works with the original CR2032 battery supplied with the Shelly BLU Wall Switch.

NEW: The design now also supports CR2430 batteries.
 

A separate battery holder for the CR2430 is included, allowing you to choose between CR2032 and CR2430.
