Problem solved, it turns out one of the brown wires had snapped. I joined them together again and voila, it works.
Thank you everyone for your assistance.
What was the conclusion of this? I have the same problem, there is power going to the switch but when I press the black nub down for 15 or so seconds nothing happens. Any assitance would be fantastic.
