these are two switches w magnets just the flat type w no holes .they are very flat . number two has a hinge made from fiberglass.
number three has no hinge and is floating . also used 40 gage ammo shell for actuator which also houses one of the magnets .
the other magnet is glued on after the switch is build . hold in place with 5 min epoxy till cured. used copper clad circuit board .
the third one is the charm ! will build more of them and use the part of the schell with the firing pin end and no other actuator botton needed . just need to know how long for different mods.all soldering must be done before magnets go in w epoxy. .
they are as flat as the dna 20 w the readout folded on .
have this in mind for a simple to build box .
