Screwless (magnetic) switches - safe??

[garrymum]

Hi

I have replaced all my white plastic switches / sockets in the house with Black nickel metal ones, bar one. This is an architrave switch for the light in the cloakroom. Up until recently I have been unable to obtain a black nikel architrave switch so I have kept the original white plastic one. I have now seen a black nickel architrave switch but it only comes as the screwless type. Presume these are magnetic. How strong are these magnets that hold the switch to the back box? I am a little concerned that my 7 year old daughter may move the switch, exposing the wires a little.

Thanks

There are still screws on the inside - it's just the bezel that is held on magnetically. No wires are exposed if you pull it off.
