Sometimes I can't find the right set of words to google what I'm
looking for (or to find it on Amazon)

I'm designing a relay module, with some number of independent SPST
power relays, and I thought it would be convenient for the customers,
if any, to be able to buss one side of some of the relays sometimes.
But without soldering.

If we had a row of holes on the board, one could bolt down strips of
buss bar as needed. So I want to buy a flat metal strip with evenly
spaced holes. A customer could, say, snip off a bit with 5 holes and
bolt it down with 5 tiny screws to cluster 5 channels.

I recall companies that made this sort of thing, electronic pcb bus
bars, standard and custom. Does anyone know of any?

Back in the DIP ics and double-sided board days, we'd sometimes use
soldered-down bus bars for power and ground distribution.Maybe some
people still do.

I could design a PCB that had various length bus bar jumper things, as
breakaways, so users could snap off whatever they need.

2, 3, and 4 hole segments might work, in general. It's an interesting
geometry puzzle.
