Thanks Rich for the links. However, I would rather have a "All Mechanical" device for better reliability.

My personal experience as a technician who works with just about every facet of engineering technology, is that electronic devices are more dependable than mechanical ones, providing they are designed well .

My experience as an electronic

My experience as an electronic engineer has made me very leary of electronic fail-safe devices. I'm a believer in the KISS principle and applying just the right amount of technology to solve a problem. Too much complexity harbors unforseen failure modes that are sometimes not discovered until the system is needed. And I don't want to loose a boat due to excess complexity. I would be much more comfortable with a simple wind-up deadman timer. Mechanical Clocks have been around longer than electronics and are well understood.

Fair enough. I think you

Fair enough. I think you will have to build it yourself, or adapt another mechanism though. I can't see anyone wishing to go to the time and expense of developing such a gadget for what would be a very small market, and even if they did, the finished cost would probably put a lot of folk off.
