“In developing the ICOS10 ASSIMILATE SENSOR HUB, I needed to verify the cables I was creating. The verification was to check continuity between the sockets and isolation between the wires. The design I came up with used DIP switches to change between continuity and isolation tests. As I expect to have a different board for each tests (the DIP Switches aren’t built for constant use), the two circuits can be hard-wired without the need for DIP Switches,
The same design principles can be applied to larger (wire number) connectors as well.”
