I know people who also use Eachen switches and love them. Just worth noting that in some cases, certain LED globes show a very low light glow even when off.
This is not true. Most South African lights switches don't have neutral. Live goes into the switch, and when switch is closed live leaves the switch to the light, neutral is then attached to the light to the DB.
As most people have said, depending on how many gangs you have, it's quite simple...
