Lads, I'm stuck and need some advice.
I need to make a through hole slip ring that's got a 70mm ID and a height of < 15mm.
It needs 3 channels and must carry occasional loads of 500mA for a lightly used servo. Rotation speed will be max 30RPM.
I've looked around and my best bet seems to be to make a PCB slipring. It seems something approachable, I just need to know where to buy the brushes. Any ideas what they're called or anywhere that sells them?
I would struggle to make the brushes by myself so any advice is appreciated. The commercial ones seem to use gold plated or a brass/copper piece of bent plate. I've tried searching for switch contacts or brushes on RS/mouser and haven't found anything.
