There are several designs but they are all built from plastic.
There are small ones like these.


I don't prefer those since for me it is easy to current jump and catch finger. For older people it will just scratch on finger but for kids it can be much painful.
Here are bigger models which are in my oppionon more safer and looks more modern. It helps do home design.


Some people don't like it since they think it can break easier than smaller one.
What do you think about electric swith? What types do you preffer?
