Possible to put 2nd light switch just outside kids bedroom?

[danceindark49]

Hi everyone

We've had to take the light bulbs out of my 3-year old twin grandsons' bedroom because with teamwork they can reach the light switch and had started getting up to play in the middle of the night - then being grouchy all day. Trouble is, when they get coughs and colds they tend to throw up at night and with no light in the room it's a nightmare trying to clear it all up. I think the answer is to put a second light switch just outside their bedroom so that the switch in the bedroom will only work when the switch outside is switched on. It looks like there are 2 live wires going into the existing switch and 1 live wire going out -presumably up to the light fitting. Does that sound right or have I got it back to front? Would I need to connect all the lives to the second switch and back again to the original switch or just one of them? Alternatively should I bypass the original switch and just take all the wires to the new switch? I'm handy with tools and quite logical so I'm sure I can do this job safely with a bit of advice from someone in the know.

Many thanks.

danceindark49,
If you have 3 wires into the switch there's a fair chance it's a 2-way light switch with another switch somewhere in the room. Relocate the switch outside the room and put the wires in the same connections. Fit a blank plate over the old light switch and don't forget to turn off the electricity before you start.

Thank you very much for the advice and sorry it's taken so long to say thanks - the boys have been catching every bug going so it's been non-stop washing bedlinen and scrubbing carpets for weeks!
The existing switch certainly looks like it's wired to have a second switch in the room but there isn't one so it's obviously one of life's anomalies. In any case, I'm going to take your advice - blank off the existing switch and run all the wires to the new switch.
Thanks again.

You can get a light switch which needs a key. Designed to test emergency lights but may do what you want.

Thanks so much for that idea. I haven't found an emergency light test switch that will do the job but I think I've found a key card type switch which means I wouldn't need to start drilling holes and running wires through walls. I don't know why I didn't think of that in the first place - doh!!
Thanks again.
