"to switch on sth" or "to switch sth on"?

Hello

I have a problem with the word order. Which of the following two sentences is correct?

Please switch on the light.
or
Please switch the light on.

Can possibly both be correct and one maybe more common or "better" english?

thank you for your help.

Neither one is better. Both are correct.
Where I live, people more commonly say "Please switch the light on."
But if there are many words between "switch" and "on", we will put "switch on" together.

That is, we would say, "Please switch on the light over the kitchen table."
We would not say, "Please switch the light over the kitchen table on."
