When you switch on, magnets in the switch get close enough to the reed switch and they allow power to the electronics.
Sometime these fall out of the little groove that they're supposed to stay in. .
So just so I understand, there is a design fault in the switch which allows the magnet to fall out causing loss of power.
Both secondary and life supporting primary have same design fault in their switch (seeing as both switches are same design)
Hmmm, to me thats a little more than a 'little problem'
if one can fall out then both can fall out....if on the same dive it might be deadly at worse or mean you cant see any ppo2 display at best
