The switch that I got from Camelback VW to replace my broken one did not
mate
correctly with the cam on the throttle shaft. I asked for a different
one,
but was told that there was only one part number and that it was the
only switch available.

I asked about getting a new cam and was quoted the price for a new
throttle body because the only way to get a new cam is to get a new
throttle body(insert angry, confused looking emoticon here).

My solution was to build up the cam using epoxy putty. It works now,
but I am not confident that this is a long term solution.

I hate the thought of spending 30-50 dollars for a new part and then
having
to attack it with a pliers to make it work. I think that selling the
switch
without the appropriate cam is not in the best interest of the consumer.
