You already have Busch-Jaeger frames throughout the flat; the adapter lets you add a Shelly smart scene button without changing the frame series.
What it is, who it's for, what it does
About this product
This is not a switch and not a smart device — it is an adapter frame. Its only job is to make the Shelly BLU Wall Switch 4 button module sit flush inside a Busch-Jaeger design-series frame that is already on your wall. There are no wires, no battery and no radio inside — it is simply a precise plastic adapter insert.<br><br>The adapter solves a familiar renovation problem: you have already chosen a single Busch-Jaeger frame series across the whole flat, and you want the smart button to look like every other rocker. The frame lets the BLU Wall Switch 4 read as a native mechanism of the series, keeping one consistent style. Note: the box contains only the adapter — the Shelly BLU Wall Switch 4 itself and the decorative Busch-Jaeger frames are bought separately.

Where it works
Use cases
A BLU Wall Switch 4 in a native Busch-Jaeger frame by the door fires a single-button 'leaving' scene without breaking the hallway design.
A designer keeps the same Busch-Jaeger trim on ordinary switches and on smart panels across the home through a series of adapters.

Frequently asked questions
Is this a smart switch?
No. It is a passive plastic adapter frame with no electronics. The smart switch is the Shelly BLU Wall Switch 4, sold separately.What is in the box?
Only the adapter. The Shelly BLU Wall Switch 4 and the Busch-Jaeger decorative frame are not included and are bought separately.Which frames is it compatible with?
With standard Busch-Jaeger decorative frames. Check your frame series before ordering — we can confirm compatibility.Does it need wiring or a battery?
No. The adapter has no wires and no battery. The CR2032 battery powers the Shelly BLU Wall Switch 4 module, not the adapter.How is it mounted?
The BLU Wall Switch 4 module sits in the adapter, then the assembly clips into your existing Busch-Jaeger frame — no tools needed.Does it change the smart switch functions?
No. The adapter is purely mechanical: it does not affect the BLU Wall Switch 4's Bluetooth, buttons or scenes — it only changes the fit in the frame.
