Does anyone know where the diagram is for the buzzers that are used at competition? I know it is out there somewhere, I just don't know where it is. Thanks in advance for your help.
"diagram"?

I don't know if there are standard buzzers... Someone that has been through NCC can answer that better.
I don't see anything mentioning buzzers, other than the judge's testing them.
To the OP - what is your intent here?
