   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.
