Dale;

That is what is used; except it has 4 pins instead of 3.  I'd say that an
indicator light that verifies the latch rods are fully inserted would be an
easy, excellent idea.

Al,

Given the critical nature of the latch in this application, I
wonder if a "bank vault" latch might not be a good idea.

Attached is a simplified illustration of the concept. A latching
handle could be constructed with a release similar to that of a
console-mounted auto transmission shifter, for one-handed
operation.
