On: I made a macro keypad with 3D-printed switches

I wasn't suggesting I'd gold plate it myself, I meant I could just buy gold-plated wire, as long as it would be sufficiently durable.

Yes, hard gold plating is pretty durable. Take a look at the plating on PCIe card and DIMM contacts. Or just about any high quality connector.

Switches have an advantage over these connectors in that they touch rather than slide. So wear and tear is much less of a problem.
