Master-switch for the current (6)

Ross

I believe the answer is:

stream

'the current' is the definition.
(synonyms)

'master-switch' is the wordplay.
'switch' indicates an anagram.
'master' anagrammed gives 'STREAM'.

'for' is the link.

(Other definitions for stream that I've seen before include "schoolchildren grouped together" , "Fly" , "Transmit music or video online" , "Small narrow flow" , "'Brook, runnel (6)'" .)

I've seen this clue in The Globe and Mail and The Telegraph.
