the ones on dx, they're not strong enough , sat my nemesis down , i thought it was holding the mod . it was nt it was firing fried my kick 2. .the dx ones are really brittle and will break . the dx magnets are
not big enough and would not slide over the pin in the switch either . so they really do not work as they are suppose to .i ended up buying 2 magnets for $10.00 good ones and added a dx magnet on the bottom .works great now .
Obviously my post contradicts yours. Knowing how to install, how to adjust and how to test will prove out my earlier response.
The Magnets do not need to slide over the pin. The pin site in the Delron when assembled and the magnets ride BELOW.
Strength is set by rate AND DISTANCE. if your switch gap is to wide it will fire before magnet force increases enough to stop motion.
All 1mm thick Neo magnets are Brittle it is the nature of neodynium. If allowed to slap together 1 or Both can shatter.
