DIY Cheap 4 Way User Port Switch

Post by Elminster » Wed Aug 29, 2012 1:17 am

I bought a 2 way user port switch from ebay, with postage cost nearly £20. And didn't work, not because it was broken but it wasn't fully wired, never had been. I am guessing it had been designed for a specific product that didn't need a couple of the user port data lines. Either way mouse buttons didn't work.

So I bought a brand new 4 port 25 pin switch, some connectors, (already had ribbon cable). And made myself a 4 way switcher for about £15 all in. Wish I had thought of that first and save myself some cash. The main cable from the switcher ends in a normal 20way idc female connector (not pictured).

Anyway just in case anyone else is looking for one I have added here with pictures below.

I should mention the dsub to ribbon cable connectors are hideously expensive, but as I mentioned I could be bother to solder up all the cables.

Standard 25way d solder cup and female IDC connectors (and then connect the 2 females with breakaway pins) would be quarter of the price per cable.
