You don't say how often you need to change the jumpers, or how compact you need this to be, or how easily they need to be changed.
But, if you have two pcbs that you can move far apart, then load one side with pins, then bring them together, you could use something like this; https://www.harwin.com/products/P70-2300045R/ There are many styles and brands of these 'test pins' Roland On Tue, 12 Jul 2022 at 11:44, andy pugh <bodge...@gmail.com> wrote: > Not CNC related, but I thought that someone here might know the answer. > > I want to make a rewirable adaptor (OBDII to DB15) > > One neat way to do this would be with a matrix, where you plug something > into holes and that connects the row to the column. > > As a CNC link (almost) I think that something like this was used on the MEC > Microsprint programmable lathes where things often called "diodes" were > plugged into holes to program the machine. > > I feel that a couple of PCBs. spaced a small distance apart, could have > plated-through holes linked by "something" being plugged through them.
