Hi all,
 
I have a switch which isn't making electrical contact. It consists of
two leaf springs. Dead simple. They're springy enough to push against
each other alright. And I've cleaned them with ethanol (didn't work)
isopropyl alcohol (didn't work) and Servisol switch cleaning lubricant
(didn't work either). I am at a complete loss here. Has anyone come
across something like this? I can confidently say I never have!

 
I have had this happen when Hypoy gear oil has got on the contacts, but
as other have said, the fault may be elsewhere.  Were you making your
measurements directly on the springs or on something attached to them?

No, I got the probes directly on the leaves themselves.

Soak some unbleached kraft paper in alcohol or kerosene, and
force between the leaves' contacting surfaces.
Move vigorously in a circular patternm, then remove and retest.

Wouldn't have bothered, if I'd known.
