Maybe they are alodined instead of anodised ie still electrically conductive

Thanks for the link. I was looking very recently for something just like
this (compact high power switch) although I’m not convinced on the choice
of anodised al-alloy screw for the primary contact load carrier; although I
assume they’ve tested it.

Hi Fred
If you don't absolutely need double pole, I've used switches like this
before:

They seem like they would be very vibration resistant. You could also
easily make your own that was effectively double pole, the poles just
wouldn't get switched at the same time.
