The original factory-fitted switch on mine had been hacked-about to get to the connectors, a real bodge.
I got my replacement on Ebay although if they are out of stock Rutter's have them (more expensive...).
It's one of those jobs that needs a universal joint on your neck, and probably better close-up eyesight than mine.
