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?

A possibly short term solution is to rub very fine folded over emery paper
between the contacts. It tends to destroy plated contacts but might just get
the switch working.
