Hi Alumn@

All three phrasal verbs can be used when you refer to electric lights.
In addition, the phrasal verbs turn off and switch off can be used to refer to other electrical devices (such as a stereo, an electric fan, etc.)

A candle is not an electrical device. A candle has a flame. None of your phrasal verbs can be used when referring to a candle. Instead, you can use these, for example:
- put out
- blow out
- snuff out
