Light switch

Just acquired a TV3 late model non chrome ring. I'm working on the headset and so far established that the plastic pulley wheels are correct for my model (changed from brass in May '65)
Now onto the light switch? Nothing fitted when I bought the scoot so no reference as to what was there. Not too keen on the new switches with the 'Hollywood smile' white buttons especially as I am keeping the original paint so could I fit a black button switch bearing in mind the year?
Thanks so far for everyones help btw.
