[QUOTE="EatonEggbeater, post: 16294687, member: 8939"] They used to use mercury switches, but now mercury has been banned- for the most part. New thermostats are SS. Wall switches also had mercury in them. A trace amount is in CFL's as the conductivity of mercury vapor allows them to start easily. But the mercury switch isn't actually a vacuum tube. One really interesting thing about mercury is that lead will float on it. He was correct on the microwave, the Klystron or Magnetron is actually a vacuum tube and is the part of the microwave that radiates the electromagnetic wave that heats food. In actuality the Klystron may (by now) have been substituted by something easier to produce, but I'm too lazy to look any further. [/QUOTE]
