I am doing some repair work to a vintage mixer. And I need to replace some switches. But I have no clue what to look for. Here are a few photos of the switches. They are stamped ALPHA. So I know that these are Alpha brand. But I do not know much else. There are ink stamps on both type of switch as well. The switch marked OG is three way, and the one marked OF is two way. Any information would be fantastic!
