Mercury

Not the car,the metal.Has anybody(other than me)ever used this to coat electrical contacts(like a switch)To eliminate arcing damage,corrosion,or the like?It's a perfect conductor,wont arc burn,never wears out.Perfect connection every time,no intermittent problems.Is this pushing the limit?

Apart from it giving of some nasty fumes, how do you get it to coat and stick to the surface?

When I was very young,my dad gave me a mercury coated penny.I thought it was cool and slick.I used to rub it all day.Maybe it helped with with my concentration.Later I coated the copper contacts on a RAM module and the edge card to stop memory crashes.A very old computer.Recently the transmission selector switch became intermittent on my 06 Suzuki car.I found the contacts were arc damaged,black and pitted.Rather than special order a $168 switch,I scraped the pads clean.polished with a pencil eraser,then added a small drop of mercury,using the eraser,i rubbed the mercury onto the contacts untill it was coated.I added a little more to provide a good layer.The excess is re-bottled.The theory is that high end burn proof switching use mercury displacement contacts.Even home thermostats,car tilt switches(trunk and hood) use mercury coated contacts.Because I don't heat it,no fumes.Just containment considerations.
