Magnetic Flux and Coils (HES Bounce Related)

i say forget the HES, and follow the crowd...go for an optical switch. Still no mechanical parts to wear out, and no issues as fas as i know with Noid interfereance....plus the masses thisn they are "hot" because of the e-blade and new angels. Then AGD guns will be able to use the "hot" aftermarked triggers also. yeah my .02

But with an opto-sensor, you require a spring as a trigger return. I think the big advantage, and perhaps the whole point of the magnetic trigger is that it behaves exactly the reverse of a spring- the trigger resistance decreases the further you pull it. I prefer a longer triger pull length, and for me the E/XMag has a positive feel, but allows a longer trigger pull length without feeling mushy, like a sprung trigger can.

Well... The emag trigger needs a return spring too. That's what the magnet in the top of the trigger, and the magnets in the frame do. they are MEERELY a trigger spring. The eblade uses magnets in the same way as the emag does.

Now there are problems with electronic eyes. If they get dirty, your trigger will fail. However, the HES can not be fooled by dirt.

However, there is a lot to be said about microswitch triggers. they're dead simple, don't have a lot of the issues other switches have :-) but.. microswitches have bounce.....

You misunderstand- the magnet provides return force, but a magnet's force decreases with travel- a mechanical spring's force always increases with distance. That's what gives the Emag trigger such a unique feel- a firm initial pull which becomes extremely light, which means you can have a long but light pull. With a microswitch, to keep it light, you really need to have a very short pull, or a very long spring. It's all down to personal taste, but I much prefer the magnetic trigger.
