Title: The RipOruster - Checking Out Switch Wear and Spring Composition
Post by: Mr. Perfect on Sat, 14 May 2011, 16:49:04

So about the switch wear part, are you going to reassemble the switches afterwards? Or is this simply a rust test?

Also, WTF happened to that IBM spring?

This seems like it might just turn out as a useful test. Those springs "could" rust, but I might not be alive when it happens.
The first thing I thought, was that you would decide with the test if water or Windex was useful or not. Do you hope to eventually decide that too?

Should be an interesting experiment. I'll have to keep an eye on this thread.

Just as a point of reference, what are the staples and nails? Galvanized steel? They haven't done anything either. Do you have an uncoated steel item you can use as a control?

What are the leaves in the cherry switches? I had thought they were copper but if they are attracted to magnets that can't be the case.

If it's sticking to a magnet, then it's got iron in it. Maybe a copper plated steel?

I thought that the Cherry ad copy implied that the MX series switches had gold plated contacts.  At least that's what I ASSumed that "MX gold crosspoint contacts" meant gold plating on the working bits.  Now what "crosspoint" means I have no idea.

Staring into the remains of this poor MX8100 that I just savaged for its caps, stems, and springs, the little contacty bits certainly look as though they may be gold plated.  Anyone have some HCl, HNO3, and a microscope that I could borrow for a few?

You shouldn't use metal (nails) to mount the stuff on the wood :3

I'm a bit surprised my the lack of any real corrosion after six months.

have you tried an oxidizer or accelerant on new springs? would give quicker and more extreme results.
