Manfred,
The high speed transfer rates of most scsi controllers would probably
not take kindly to switchboxes. Scsi controllers transfer data at speeds high
enough to generate standing waves on the cables, which is one of the reasons
for the need for terminators. When you start mixing cabling, connectors,
switches, etc., you are creating a potential for problems created by both the
standing waves and possible "crosstalk" between signal lines inside the
switchbox. The result might very well be an unreliable scsi chain. Obviously
there are solutions to these problems, but their costs may well outweigh the
benefits.
