I still have a small vial of mercury I removed from light switches almost 50 years ago.
There is a "pellet" with metal on both sides, separated by a glass or ceramic bead. When the switch is tilted up, the mercury makes electrical contact to both metal sides and a hole inside the ceramic bead. I was 10 years old at the time, and we were very nervous about breaking the bead because some mercury compounds are explosive (mercury fulminate). After debating a few days, we cracked it open and course we were enthralled with the mystery liquid, but we knew it was toxic and never touched or heated it. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
