Touch switch and wall socket cover. Fits perfectly on Sonoff / identical touch switches and Busch + Jaeger sockets.
Ensure to have a suitable support for the socket's inner part (see photos). Use the small cover to make it look better when no plug is inserted.
Use a 5mm drill to clean the holes from scruffy filament remainings
This model fits perfect for my stuff at home. If it does not for yours, either modify it properly or don't use at all. Do not make changes to electric installations if you're not a professional, or at least you really know what you're doing. Never use electrically conducting filament.
Use at your own risk!
