No, a faux hybrid top cap allows a standard 510 atty make connection directly to the battery. They can not fail, they are nothing more than a metal disk with 510 threading. They are marketed as providing, and do provide, a direct atty to battery connection for decreased voltage drop, they are not marketed in any way as a safety feature.
The issue lies where unknowing people use it with an atty that is not suitable, i.e. an atty with a 510 pin which does not protrude enough/at all from he surrounding threads allowing the battery positive terminal to make contact with both the positive and negative paths on the 510. This is what causes a dead short.
I suggest new terms/words for connections. Hybrid needs to go, too many people already see it as different things.
DTB mods - mod side, no 510 pin within the battery housing.
This is my point, wording.
For one thing , no one has posted an idea of where this hybrid term came from to begin with, what the originator of the term meant. Yes the term is tossed around like candy stickers at the voting machine.
I've learned through life that anything can fail given the proper circumstances, a hybrid connector is not out of the realm of failure in any sense. As with anything , the more complexity, the more possibilities to fail.
Not taking the mechanical adjustable top cap into play in the above scenario, failure would edge on the side of the end user.
Issues cannot be fixed if the root of the issue is not known. Some of this has the appearance of complete and utter sheep following the sheep. Then by osmosis this mis information, mis wording and terminology is passed on to the next user.
