I'm planning to build some attenuators with 12-step rotary switches. The switches have one set of soldering lugs by the switch. Where can you get the round PCB boards for the back of the unit?
Follow Ups:
there is no need to use pcbs, just solder the resistor directly to the
lugs, if you have the schematic right, you should be able to do that easily. The easy way to find the resistor value for each position is to use a potentiometer connected with aligator clip at one end, and try different position on the pots, then use a multitester to test the value

I was planning a parallel shunt attenuator -- need a ground plane. It seems like I can just use a little square of perforated breadboard.
