Having Smart lights in the house we needed a solution to stop us flicking the switches
These are idea for single UK switches.

Simple installation:

• Unscrew Switch faceplate slightly.
• Slide U shape part up from the bottom
• Tighten face plate
• Slide cover down from top

Depending on your bed adhesion i would recommend a decent brim on this just to hold it flat.

I recommend 0.16 because this is my preferred rez but nothing stopping it working in 0.2
