Take positive action in current affairs (6,2)
I believe the answer is:
switch on
'take' is the definition.
The definition and answer can be both to do with contact as well as being verbs in their base form.
Perhaps you can see an association between them that I don't see?
'positive action in current affairs' is the wordplay.
I cannot quite see how this works, but
'action' could be 'switch' (switch is a kind of action) and 'switch' is found within the answer.
The remaining letters 'on' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for switch on that I've seen before include "Operate" , "get to work" , "set off" , "trigger" , "Make contact with" .)
