Exposing my ignorance: When you use an IEC inlet without a power switch, especially an inlet that has copper contacts, what do you use for a power switch? The number of power switches on Mouser, RS, & Digikey which handle 10A or more, 250VAC, and have copper contacts & switch elements seems limited to Panasonic and NKK and none are round either.
It seems like anything less than the above would neutralise the benefit of having a Furutech FI-03 IEC or the like. Or is there some simple trick I can't find? Of course Neurochrome has a softstart circuit board that allows a low amp switch to be wired in without impacting the power quality or current, but that is rather complicated and expensive so doesn't make sense with an external LPS feeding digital gear or even a lot of preamps.

I think you're a bit stuck for a round quality switch, Bruce. I normally pick up power buttons from Switch Electronics. They don't fail, they look good, and everyone loves a ring LED |

I think you're a bit stuck for a round quality switch, Bruce. I normally pick up power buttons from Switch Electronics. They don't fail, they look good, and everyone loves a ring LED Thanks for the signpost. I'd been looking at DPST switches but it looks like I should be looking at an content with SPDT switches. Of course, putting a ring LED switch up front sure lengthens your AC leads inside!
- Are you then using the 19mm 21A switches with 6.35mm tabs? It seems the 5A and smaller switches use 2.8mm solder tabs which seems a little small for best current flow. Maybe I'm unrealistic.
- The datasheet says the contact material is silver alloy. Is that meant to mean solid silver alloy or plated over brass?
- If I'm willing to make another square hole, Panasonic has copper contacts. It's just more work.
- One thing I've always been unclear on: since it says the illumination voltage is 12V, does that mean it needs separate supply for the illumination or just will be ultra bright with 245V?

Separate supply in my experience. I can't recall which ones I bought last. I've taken to stinking massive toggle switches on everything these days lol |
