switch back
(to something) 1. to return to using or doing something. I decided to switch back to my old shampoo. I switched back and was glad I did.
2. [for a road] to reverse upon itself. The mountain road switched back twenty times in three miles. It switched back every now and then.
switch something back (to something)
to return something to the way it was. I switched the television back to the previous channel. I switched back the channel to what I was watching before.
