Magura,
I think lots of people are interested; but there's another issue; time. You have to hit them at the right time; most people are completely disinterested in other aspects of their projects until they get to it; they develop everything serially.
I must say I like your icon; that girl has quite a presence......
Cheers,
Hugh

You would have to be able to make the parts yourself, else it would become a 1000+ USD switch. I have estimated a minimum of 10 CNC machine hours which translates into minimum 20 conventional machine hours, plus another 15 man hours at least.
A CNC hour is at least 75USD around here, conventional machine hours are like 50-60 USD here.
This was aimed at guys like Chipco, EKD and the like

Maybe you could team up with one of our members from India who could produce and export.
I understand and applaudyour effort. If I had the time and a lathe, I would build one just for the learning. If I had a large CNC mill, I would machine some huge heat sinks out of 50 Kg blocks of aluminum, just to have the boldest and most expensive heat sinks.
Get to it mate. I want to see this masterpiece.

I have no intentions to make this a commercial effort, if I had, I could produce the switches myself for about the same price as they can in india, as its a matter of machine hours if made in larger numbers, and a machine hours price is defined by the price of the machine, not the location.
Hmm, huge machined heatsinks...wait a minute
didnt I make a bunch of those a while ago

6 kilograms a piece
Made 12 of them for my zen project.
Still got a lot of deburring to do
The point of this exercise is though to get around some of the issues the commercial switches have. Naturally there is a reason for elma and the like to not make such a switch as Im working on. The cost is a big factor, a limited target group would be another reason not to make such a product. I guess such a switch could be retailing for around 500-600USD for a single layer switch, that would keep pretty much any potential customer at bay I guess???
I guess its time for a quick description of what this exercise is really all about.
The point is to get rid of the steps in the listening level, I am aware of that the steps cant be 100 % eliminated, but at steps smaller than 3db, it should be bareable.
Second aim is to make a switch that will virtually last for ever, sealed, solid silver contacts, BeCu slider, titanium springs (or ceramic if I can get my hands on such) and dampened CuBe shaft.
Add a handfull of ballbearings and you got the full picture

Update:
Did the CNC programming for the plates that holds the contacts and the resistors today.
Mark from canada (a member as well) have sorted out the 3mm PCB for this part, it is on its way to Denmark by iceberg hopping eskimo as i write this.
I hardened the die for the contacs today as well (see pic in earlier post).

Titanium wire or thin sheet would also do the trick, but is just as hard to find.
Cheers
Magura
McMaster-Carr carries Titanium wire and sheets. Just search for Titanium, and they have a wide selection. I didn't see any ceramic springs on the site. If you want, I can place an order for you and ship the stuff to you, via USPS Global Priority. The prices should be favorable now with the low exchange rates. Drop me a mail if interested.
