A curiosity I can’t understand. Can anyone explain what’s going on here?
I have a light controlled by a normal two switch arrangement (I can turn the light ON or OFF from either of the two switches). Works fine 99.9% of the time. But every now and then (maybe twice a year), I find that one of the switches fails -- snapping it (many times) has no effect. But if I snap the other switch, just once, then everything returns to normal and both switches work fine again. A puzzlement.
