Solder, man, solder.

I do, too, but only if it improves something. Or if I can't find the correct terminals in my kit of miscellaneous electrical leftovers. Or if I just feel the need to melt stuff.


And anything that can be made and shipped all the way from Chairman Mao's orphan farm straight to your door for a measly seventy-eight American pence are suspect enough when dry. Get those brake cable switches wet and I suspect they'll go full-tilt Gremlin on you.

Is there a motorcycle salvage yard anywhere near you? A road-legal bike or scooter with cable-operated brakes will have some sort of mechanically-operated brake light switch, and it should be more or less weatherproof.
