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!

Have you verified that the meter leads are making good electrical contact to the switch blades? Oxidation can fool any of us! Touch one probe to the switch blade, and touch the other probe further down the blade - repeat on the other side, only then check for electrical contact closure once you are certain you have good probe connections.
