After a search - the green knob (and other colours) switches all look very alike with prices from A$6 to A$20 . One was marked Taiwan and described as brass coated zinc.
My three are up to ten years old and still in good condition but if zinc (mazac or similar) I would think not that strong.
As far as I could see all were for the negative earth battery post- as are most early sevens.
