Answer

You can briefly explain the reason, that will make it more polite.

Please, do not touch this switch because...If you need to turn on/off the light, call Mr. A (room 000).

Answer

you could say "Please do not use this light switch!"  or "please refrain from using this light switch"  hope this helps answer your question
