On the picture I have included I have numbered the leads.  Can you let me know which two are ground?

As 2 of them are supposed to be ground you could check for continuity between them, the 2 that are connected would be ground. 

 

Edit: Viewing the PCB images in post 1 I can see that the inside pins(2&3) are connected to the ground plane, while header pin 1 connects to socket pin 27 and header pin 4 connects to socket pin 1.

Thanks .. what I thought.  Did not think of checking for continuity.

The DP4T rotary switch below looks small from the images, unable to confirm but think the pin spacing is likely 0.1". It's the only one I can find at a reasonable price that's easy to mount.

I bought these and they work great both in size and function. Thanks!

I have 30 of these 4xOS PCB's onhand. It might be a while before I get a chance to build them up, so in the mean time I'm making these available if you're handy with a soldering iron. Actually I can probably throw in the headers, socket, and resistors too. :) Extra if you need a programmed EPROM.

-- $5ea, postage $2 Canada/USA, $3 International

 

Or wait until I have some more assembled.
