Default threshold 400 A

Does any body have any wiring info on connecting a new on off power switch .The old switch is gone so there is nothing to copy.
Is there any thing special or just hook the red wire on 1st side the the white on the other to complete the circuit when activated.

That's great. I would bet it's Bill Hoffman's work.

I got my switch from Jon Soderberg (http://www.vintageamprepair.net/) and it was no problems connecting it. I can open my 400A to have a look for you though. To see what I did!

PS All those scans promised are on hold. Too much other things to do right now.
