F430 start switch out

The switch alone is not available from Ferrari. They offer onlt the complet wheel. The switch itself is a complete assembly and ties into the sub harness internal to the steering wheel.

 

I'm sure the part is a standard switch. You should be able to pull the wheel and harness apart, see a part number and just order a new switch from a place like Mouser. You may need to do a little soldering, but no reason to buy a whole wheel.
