I know this is a long shot, but I thought I'd offer them before they go 
to the tip...
I have 2 switch-boxes with 25-pin D-type female connectors: one is a 
push-button two-way switch, the other a four position rotary switch. 
Both are completely mechanical, so they can be used as concentrators or 
distributors. If you're interested, please contact me off list. I live 
in Newbury.
