strongarm

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

'astronaut switching' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'components using a lot of force' is the wordplay.
'components using' becomes 'strong' (I am not sure about this - if you are sure you should believe this answer much more).
'a lot of' means to remove the last letter (most of the word but not all of it).
'force' becomes 'army' (army is a kind of force).
'army' with its final letter taken away is 'arm'.
'strong'+'arm'='STRONGARM'

Can you help me to learn more?

(Other definitions for strongarm that I've seen before include "Show violence towards" , "Bullying" .)
