finally got around to buying a 500k push/pull to wire in as a blower switch. here's what iv'e come up with:
only thing is, i never got to finish it because of my neat little fuck up here
i'm not exactly sure if my diagram's correct and i'd like to know if there's a much cleaner/smarter way to wire it all up. also, what would you luthier-expert-types suggest when grounding to the push/pull pot? the heat from this first attempt caused the actuators in the switch to fuse together, effectively flushing $13 down the toilet.
a) Not sure about the wiring - I'd need to look at it when I'm more awake but there are many people here more knowledgable than I on this subject
b) Sand the soldering surface with some sandpaper. You just need to rough it up and remove the oxide layer. You may find a copper-like finish when you sand (and we aren't talking about sanding much - just get a shiny bit of metal). This massively improves the electrical connection and makes it easier to solder to. I do my pots at a higher heat than most, as it allow me to spot-heat the area I want to solder quickly and then attach the pot to a heat sink (i.e - a kitchen sink) to cool it down quickly. At low temperatures your iron will try and heat the entire thing which is probably what caused the damage the first time around.
