Sorry about the picture quality. I'm shit

This is what it starts life as
After drilling the casing off, this is whats inside
4 wires on the bottom VERY fragile
After un screwing the bit that slides in and out this is what your see
Then to split it down again, bottom piece with magnet on the left, top piece on the right
The bottom bit
This is the slider screwed into the magnet. The magnet spins and pulls the slider down by tightening the thread.
The top bit. On this one i notice it was cracked and was restricting the movement in and out of the sliding pin. THATS why this one failed
Crap pictures unfortunately. But you can see that this model has 2 groves to keep it striaght when it moves in and out. Never seen this design before and i reckon it could be the best design.
Full exploded view
Now make your own mind up as to why they fail.
I still would like other models that have failed to see if there is any difference and see how they fail
