Re: Fuse NOT blowing

The switch includes a horseshoe shaped beryllium copper spring mounted on a plastic insulator by rivets which makes contact with two brass pillars that have the cables connected to them. I suspect that either the rivets came loose and allowed the spring to contact the body of the switch, or perhaps the insulator had 'cooked' and become conductive. Either would allow the current to flow through a 'short' circuit to the metal parts of the vehicle through the spring to the brake pedal. The switch is a very common type and not worth the trouble of trying to repair it, even as a spare, but it could be interesting to see EXACTLY what caused the original problem.
