I'm in search of some steatite switch wafers for a broken switch and in my searches, I have found many instance where the Centralab wafer model number has a one to three digit designator (e.g. D, DD, PA, PS, PSY, etc.) yet I have not found anything that describes what those designators indicate. Does anyone know about those?
Specifically, I'm looking for some 1-POL, 11-POS non-shortingwafers (where the wiper and the other contacts are all on the same side of the wafer). Additionally, I need them to have the wider hole spacing (where there's a slight elongation of the wafer 180-deg apart to accomodate a wider set of holes).
I think I can find some that will work but I still wonder what those designations are all about.
Thanks,
