Relay - alternative to mosfet Thu Apr 09, 2009 2:59 pm
Mr.Lee
Here's the actual relay and diagram I'm using recommended by Sir Elaz.
I think this is the smallest relay you can find on any SURPLUS shops
price range 70-150 petots. Just ask for a horn relay with a 3 contact pins
and make sure you open it up before buying it coz sometimes either they are busted, rusty
or heavely worned out already. Get the cleanly coiled ones.
With this relay connected to your AEG you'll have a burn mark free trigger contacts
all year round especially if you have a highly upgraded gun and loves firing
at semi. It will save your trigger contacts.
Note - really follow the diagram or the relay won't work at all. You'll know if ain't working
if you still see some arcing/burning on the contacts when you press fire.
Some vids showing that relay do works.
Without a relay. Shows that pesky arcing/burning that simply eats up your
contacts which you'll need to replace once fully burned out.

With a relay. No more sparks or arcing or burning.

Pros and Cons using a car horn relay...
pros...
- way cheaper and easier to find than mosfets IF you buy the 2nd class types of relay at any surplus store.
- Doesn’t over heat
- can handle very humid or rainy weather (since car parts are subjected to harsh environments)
cons...
- a bit bulky very hard to hide on smaller shorter guns
