MOSFET question: Plug in VS wired?

[Jbone 11 11]

I've been reading up on the use of MOSFET's and have been lookign around at different brands and such.
Recently I came across this:
http://www.torontoairsoft.com/Burst-...it_p_1640.html

And am wondering what the difference is between that and a kit that you have to hard wire into your gearbox?

If this plug n play thingy works, why would you mess about with hard wiring a unit?....sounds to good to be true...must be a catch...like it's not gonna save your trigger contacts from way back there by the battery?

I think you answered your own question, albeit simply.

with a plug in unit you still have to rewire your gearbox for it the same as a hard wired unit, however when the hardwired unit fails your gun is down. with a plug in unit you can swap to a different one. Depends what you have room for inside your gun.
Both will work no matter where they are on your gun.

If you do not have to rewire it, it is not a mosfet.

Yes, even if they say so.

Edit for clarity:

Think about it, if the current loop still passes by the contacts, how will an electronic device prevent the mechanical contact of the trigger from having any damage?

See...that's exactly my understanding and why I thought I'd ask about this particular product. That said, it does half the job of a MOSFET....it should still be able to manage the electrical current like a hardwired version from my limited understanding..i.e. more efficiency, ROF.

But the physical protection would not be there....sometimes its good to talk these things out.

MOSFET has "more efficiency" because when the MOSFET is connecting the circuit, it have less resistance than the trigger contacts. If the main current still pass through the trigger contacts, it is not more efficient. Same applies to the slight ROF increase with the MOSFET.
The plug-in "MOSFET" can do a burst fire control, and probably a ROF adjustment, but not the benefits related to the less resistance of the MOSFET, and of course it can't protect the trigger contacts.

^ what he said

And there are TWO reasons to get a mosfet; to save your trigger contacts from the very damaging effects of arcing, which the plug in accomplishes by essentially soft starting the circuit. But also REDUCING CURRENT IN THE TRIGGER. The main issue with high voltage batteries is arcing, so if you eliminate or reduce arcing, everyone thinks they're good to go on high voltage batteries. Until they melt their trigger contacts because they were putting way too much current through the switch and it melted all the plastic around it.

He is not talking about units like the MERF 3.2 that connect the trigger wires and power wires via plugs (they still require soldering the trigger wires on the trigger contacts), he is talking about units like the Burst Avocado which do not have extra wires to the trigger, added to the AEG without change the stock wiring scheme. Simple to install, but does not do the most important jobs of a airsoft MOSFET.
