touch-latch/push button magnetic lock for walnut lockbox

i build custom lockboxes (imagine a half-size blanket chest) that contain hidden drawers and complicated homemade neodymium magnetic locks. all of the locks are hidden, and itís more of a puzzle trying to open them (similar to puzzle boxes). anyway, i donít understand the inner-workings of a touch-latch. these are commonly called touch-latches, or push latches, or magnetic touch latches. they are often found on entertainment centers or cabinets that have glass doors. when you push the latch it, it moves from the extended position, and snaps back into place inside a spring-loaded core. when you push the latch again, the spring-mechanism releases, and the latch returns to the original extended position. can someone please explain what is inside the core that allows the latch to lock into place, and then returns? i imagine thereís some type of twisting involved, but im just not sure. i would like some instruction on this so i can build a homemade version, much larger with more length to the latch. thanks for your response!

The latch works exactly like a retractable ballpoint pen. has that little wedge with a tee on it to flip from side to side. ( not the revolving kind.)

Find a pen that is see-thru.

I cut it 3 times..... and it's still too short.

Dont go ninja'ing anybody that dont need no ninja'ing...

is there a specific name for that type of mechanism? the only ballpoint retractable pens i can find specs or drawings for use the rotating teeth mechanism, and that is to complex and time consuming to make out of wood.
