IKEA Trådfri holder

Square Trådfri on/off switches have magnets and metal plates which are fixed to the wall.
- The magnets are quite weak and switches are easily dislodged.

Thus, a holder for the switch (with a magnet) with additional walls to keep the switch still.

I glued a magnet to back of the holder and used double sided tape to fix it on the wall.
Circular magnets are from aliexpress, 12mm x 1.8mm
