I believe the answer is:

chop and change

I'm a little stuck... Click here to teach me more about this clue!

'switch from one to the other' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'hand cop out coppers' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'coppers' becomes 'change' (I've seen this before).
'hand'+'cop'='handcop'
'handcop' is an anagram of 'chopand'.
'chopand'+'change'='CHOP AND CHANGE'

'and' acts as a link.

Can you help me to learn more?

(Other definitions for chop and change that I've seen before include "Blow hot and cold" , "Keep on altering things" , "Vacillate - keep altering plans" , "Seesaw (metaphorically)" , "Make alterations" .)
