Re: Child-proof reset operation
push-turn UK bayonet socket type
I prefer these too. Traditional ES bulbs are also vulnerable to exposing live parts. It's less of a problem these days with properly designed fittings, but you can still see the edge of the metal screw in this modern bulb. Properly wired, this part should be neutral (which isn't necessarily safe), but if the wiring is wrong or if such a fitting is connected using a non-polarised plug you can never tell!
Bayonets do have one disadvantage however, and that is that it's possible to break the lamp - possibly leaving exposed mains wires - if you aren't aware that you need to push down before twisting. Such might be the case with a determined small child. It was worse with glass envelope incandescents and CFL type where you might also break the glass, while well-built LED types are often a bit more robust.
The drilling is great. My mum trained at the Fröebel academy in the 1960s and ran a nursery school for many years by those principles. Scrap bits of wood, saws, hammers and nails were very popular with the children.
