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!
