There is a difference between "mercury wetted contacts" and using mercury as a contact. These fit into the latter category. For more info please refer to their literature... http://www.mercotac.com/html/literature.html
All of these documents discuss the need to correctly dispose (must be recycled) of these contacts due to the mercury they contain. In almost every paragraph of the two application sheets, connector failure is mentioned as a danger. In the case of a mercury spills on an FRC field does the amount or cleanup procedure really matter? Any is too much!

Al,

I think the underlying theme of this thread is that the FRC rules have been unclear, at best. It looks like your opinion is clear so please help reduce an obvious Q & A question and use your influence to get the 2015 FRC rules to be clear on this issue.
