Nothing, it is what all switches do when switching in air, but it should be quite brief. If it is not brief, then it suggests the switch might be worn.
Why do some double socket spark when you switch them on/off

Buy sockets without switches or metal ones you can't see through.
As said, though, you must be switching them with a load still on. Switch off the appliance first.
They will still spark, you just will not see the spark.
Then the appliance switch will spark instead.
Dare I suggest just blinking, when you throw the switch, so you don't see the spark?
Any switch which makes or break when carrying current, will spark, there is no sensible way to avoid the arc as the air and metal in the gap is is ionised.
The duration of the arc can be reduced if the switch has a snap action where the moving contact moves rapidly away from the fixed contact.

Although my question may have seemed flippant it was actually serious. I thought you may have written them the wrong way round but after your explanation I can fully understand. Sorry if I caused you any offence, it was not meant.
