My cheap ebay replacement failed for the second time yesterday… a week earlier and it'd have caused the bike to fail its MOT so at least its timing was slightly off. :lol
There was masses of corrosion in there again, despite having been well flooded with switch cleaner only a couple of month ago when it last happened, but the main problem is the spring: it's just like mild steel, way too ductile. I squished the coils closed and attempted to harden it by heating it with a hot air gun and then quenching, but don't really know what I'm doing… though it is working (for the moment).
I'm tempted to try a reed switch with a magnet embedded in the lever, but it'll need a relay or transistor to boost the current handling capability unless I change the rear lights to LEDs.
