Does anybody know where you can buy the diagnostic and command push button switches on Williams sys 6 cpu boards. They are a momentary action with one nc and one no contact. It's pictured below. I have looked at all the usual places GPE, Futurlec but I can't see them. I know you don't really need them or I could substitute an equivalent not board mounted but am repairing a board with some corrosion and would like to make it look original.
Thanks for any suggestions.
