I once saw one of these mercury relays detonate.  I suggest keeping a clear lexan box around the top, and a catch tray underneath in the event that it should burst.

If you get Mercury on the floor it's a bugger to clean up.  The little balls run everywhere and hide in all the cracks.  People are terrified of mercury vapor, so clean up becomes more of a chore in paperwork, than in practice.

You can't vacuum it up due to fears of it vaporizing.  You can't soak it up.  You basically have to mechanically remove it through patience on your hands and knees.  If you research you may find people suggesting that you sprinkle sulfur, or other binding agents.

the trick with all these things is to hire a professional outfit one time.  Watch everything they do and ask lots of questions*

There's nothing magical about hazardous work. . . 

Anyhow,
I have had great luck using really large DC contactors.  Say, those ready for 2000 volts and 500 amps.  They utilize precious metals and inert gases...  And this really is better than Mercury switch is in my humble opinion.

But that doesn't address bouncing.  Good luck in your adventure.  I wonder if a really big SSR would do the trick?

The required switching current is a rather important parameter.
