correct, just don't forget to use diodes.

OK. I think I understand the matrix concept now. You can have 5 switches
with one side of each switch connected to the same connector (conn 1). But
then the other side of each connection would go to it's own connector (conn
2,3,4,5,6). So whenever a switch was thrown you would get one of the
following - 1-2, 1-3, 1-4, 1-5, or 1-6. That right??
