Item that presses switch as on timer (5,4)

I believe the answer is:

steam iron

'item that presses' is the definition.

'switch as on timer' is the wordplay.
'switch' indicates an anagram.
'as'+'on'+'timer'='asontimer'
'asontimer' is an anagram of 'STEAM IRON'.

(Other definitions for steam iron that I've seen before include "Clothes presser" , "Clothes finisher" , "Appliance for pressing" , "Tool that dampens and presses" , "Domestic smoother" .)

I've seen this clue in The Telegraph.
