I don't think any manufacturer in the U.S. has made any mercury filled thermometers for quite a while. It's probably an Environmental Protection Agency thing. That may well slop over to any other industrial product, such as mercury switches. Thing is, once mercury gets into the environment, it doesn't readily combine with other elements and become in innocuous chemical. It stays nasty...
I've been out of the business for quite a while, so I don't know how inventive they have become for replacing mercury switches. Seems that would be a bit difficult! keith whaley Rob Studdert wrote: > > > I don't think so, mercury switches are probably banned here in North America. > > North of the Rio Grande at least. > > Mercury thermometers too? > > Rob Studdert > HURSTVILLE AUSTRALIA
