The switches are, literally, 20 years old. I'd rather just get rid of them and find new if I could.
Autoparts stores, funny enough, have the relays... but not the switches. Just like the online-electronics supply places they have plain toggle switches, but not many momentary switches. I posted a link to a switch that I think will work but the forum qued it for approval. I apparently can't post links.
It's digi-key part number SW311-ND
The problem I have with it, is the picture shows it as if it is not a momentary switch. I dunno if the pic is wrong or I am misunderstanding what kind of switch it is.
