Thanks to everyone for the assistance and connection to the thread. Exactly what I am needing.
I find out Jeff's fix in 2 hrs. Waking at my usual 2:00 am from the time change. I thought Ambien CR would last longer...grrr..
Waiting until 7 when the camera will be available to me again. Reading more than I expected this trip...rather than sleeping.
Both Aquatica and Nexus housings have the issue at hand. Not certain about other housings but its likely for triggers. The tiny stem Nikon used for installing the flimsy fire button is not strong enough. Its all made for a vertical down push. We all are using a finger trigger that presses across the button, not straight down. It does not take the stress well.
Another woman here has an Aquatica housing. She has had it only a few months but dives often. The 'chrome' color has already rubber off the button. Breaking in the future is likely.
So glad Nikon saved the $0.50 or less a metal button and stem would cost. We certainly would have resisted that extra price when buying.
Jeff Mullins mentioned he sees the same with some Canon models but I did not ask which one's.
He felt certain he could fix it last night. Seemed like he has fixed several Nikons and Canons with this issue, from the sound of it.
JimSwims,
Jeff Mullins suggested perhaps removing the rubber cover of the housing 'fire' lever. Then the metal could at least slide across the plastic camera button. He was considering installing something on the camera fire button to allow better sliding but not certain what. The rubber part on the housing prevents sliding easily, adding to the stress on the stem. Not certain how this effects the trigger moving distance however. The trigger feel is so nice on the Nexus housing, I am hoping I can get this fixed without losing that feature.
If I can survive with my wits, I will try to have a matching part machined out of stainless steel when back home. I have a machinist friend that seems to like challenges. Getting the tiny nearly worthless stem drilled out of the camera will be a challenge however but I will leave that to him as well.
If he makes one and it works, I will ask if he can make more and I will offer them here for no profit to me to whoever needs them. Once setup, I suspect he might be able to make them easily but I am not certain...not knowing that trade well.

Know that little black plastic block for the housing front that is for installing the WAY overpriced Nexus spotting light fixture? My friend machined one of aluminum with a 1/4-20 thread and holes for installing on the housing front. I bought a ULCS 1/4-20 thread to ball part and it all works wonderfully. A bit of galvanizing paint covers the new Al part. Works great with a big blue light on an arm, with some bouancy additions. I rigged up a little bouancy addition, let me know if you want any details.
And as expected, The Liberty dive with no camera was perfect. First time with no current this week. Fish coming up and nearly bumping my mask. HUGE bumphead parrotfish with no cares in the world, posing nicely. If the camera is working again today, I expect that will all be over. But, it was nice to just be a diver again for a change...enjoying the lovely scenery and not feeling the internal stress of trying to accomplish something in particular.
