I was reading an article about wall switches and came across a mention of
how they used to be constructed of mercury. The article went on to say that
aside from the obvious problems associated with mercury, the switches
themselves were superior in action, quiet, longest lasting and most energy
efficient. It kind of begs the question to me - do any of you all still
have mercury switches in your house and if so - are they all that wonderful?

came across a few today still working fine in an apt. the only time i
seem to replace them is when asked to do so.as far as better probabaly
seeing things made today are not made to last, no money if your not
periodically replacing them.
