I have an oddball 5-way that I removed from a customers guitar that needed a superswitch. I think this came from a Washburn, but it's been a long time ago. The switch is only 1 1/32" deep, and the terminal come out of the side. One of the cool things about this switch is that you can simply remove two 3/16 (5mm) nuts, and have full access to the contacts so that they can be burnished or polished. I've polished these and treated them with Deoxit. This thing could last forever.
If you live in the US, shipping, with a "bubble" envelope, would probably only run $5 - $6. Round it up to $10, (to cover a beer :beerchug

, and it's yours. Remember, it's a "used" part. Just a thought.
