The switch, man! (3)
I believe the answer is:
rod
I believe this clue is a double definition.
'the switch' is the first definition.
(I've seen this in another clue)
'man' is the second definition.
(Other definitions for rod that I've seen before include "Long bar or pole" , "Baton, pole" , "Angler's pole" , "Fishing implement" , "Rigid stick" .)
