I've read countless posts here about people having switch failures, SL PP 4AA Lux, SL Jr. Lux, Kroll problems, on and on. It seems like the switch is the one component that fails in a flashlight the most (aside from incandescent bulbs burning out). This leads to my question: why aren't companies putting more reliable switchs in their flashlights? I know most lights you buy don't have problems, but it just seems like there are far more problems than there should be with such a simple component. All it's suppose to do is close a circuit, for pete's sake...
