Grayhill rotary switches

[macfixer01]

Hi,
I know I read somewhere, sometime that these were a relatively high-yield item (hopefully it wasn't in somebody's sale hype?). Has anyone here ever processed any switches similar to these and have an inclination one way or the other? I ask because I was considering buying some boards that each contain one of these and not too much else worthwhile. I'm not asking for any specific numbers of course, just opinions, but they do look pretty nice. Here's a picture showing the type of switch I'm referring to.

I couldn't see your link without registering.

Which series switch are you looking at? This data sheet lists silver alloy stator and rotor components on the mil-spec switches.

It done the same thing for me, but when i click backwards and then forward again it shows up.

Hi,
Sorry about that, I have no idea why you'd need to register for anything? I just showed that picture as an example and found it using a Google search. Maybe it bypassed the normal route to it that way? It's weird but now that I go to that link I got a log in screen too. Well I don't know the part number. As I said there's a lot of boards for sale I saw pictures of that I don't have direct access to, to look at. I saw some of these switches disassembled once which is why I recognized them. The ones I saw disassembled had chunky looking gold-plated contacts though, I didn't even realize they made this line of switches available with silver contacts?

Here's what I should have done the first time, I'll just download the picture and attach it below.

Wow, nice site. I found 8 of these a few weeks ago, ones 'double stacked'.
They want US$35 each.
