they're quite cheap so modifying one to fit will do the same job and wont cost a lot.
i think you might be hard pressed to find a vw origenal unless you can pull one out of another vw varient car.
Funnily enough, that's the same conclusion my better half came to, being an electronics engineer. As these are thin on the ground @€60 + postage, knowing that it is a waterproof microswitch worth around £2.00, bit of a no brainer for him.
However, when stripping the old switch down to remove the wiring, he found the switch still worked, it was just missing the 'button' that protruded from the housing. So, armed with his CAD knowledge, he drew up the 'button' and using the 3D printer, made a new 'button' which was duly fitted and presto, one working throttle switch - the idle of the car is now controllable!
