deskthority

Hey, I found an old cherry Board (g81 - 1000 HCD) made in 1984. I have an issue with one of the connections of the membrane being so corroded, that a few keys dont work. In order to fix this I have to remove at least one switch. However these switches seem to be riveted on the back plate. Are there any ways to remove these without drilling them out?

I'd cut off the protruding part with a sharp knife - leaves space to later fasten those back later with a short self-tapping screw.
