I may be wrong but why could you not use small air cylinders submerged in
transformer oil.
the cylinders could be controlled by air suppled by plastic/silicon tubing
and the
cylinder itself could make contact
with a buss bar or could throw a on/off lever made of tungsten. The system
would
require a small air compressor (one of those
emergency tire pumps should work. It could also run off of the 12V gel cell).
Just a thought. I may be missing some safety issue.
