The latches are used only to seal the light on the surface, = later on the water pressure takes over... But this can mean 500 kg force = on 100 m depth. Is that good for the O-ring. Why is the seat (recess) = for O-ring made that way to protect the O-ring from these excessive = forces? Sure if the O-ring is pressed by 50 kg it would seal enough, so = there is no need for the O-ring to be loaded by 500... Would another O-ring that would seal sideways not only one frontal do = any good (if the first one leaks)? Why not. I am sure there is a reason behind it all and obviously it works great, = I would just like to understand the reasoning behind it. I think it is = not only cost related....
