Title: Wafer Switches Pin Numbering
Post by: W7SOE on March 16, 2015, 06:11:51 PM
Hi All,
   Is there a "Standard" way or common practice in determining the pin numbering of wafer switches?

Thanks

Rich

Not that I ever saw.  Most wafer switches are made special to order.  Other than that, there are standard types, number of poles times number of positions.  Wafer switches are made a thousand different ways.

Thank you.  I was just wondering if there was some scheme other than studying the contacts.

Probably it's more specifically defined by the manufacturer.

Here's one:
