Lil,

Check out the attached doc on mag switch and installation. It was written for a seawind, but I am sure it can be made applicable.

Ideally you get a normally closed switch, so to kill to power you put on the magnet.
Unfortunately, a normally closed magnetic reed switch is uncommon as most alarms use normally open. That and they are rated fairly low on the amperage scale.

Right on.

This switch can be wired either way, NO, or NC, so I'll do it so that with the magnet off, the receiver is on.

Don't want a big ugly magnet sitting on my boat while sailing anyway, and as Chidago just pointed out, it might get dislodged, with dire consequences.

Actually, I'm considering using a small rare earth magnet as a trigger anyway, so if that works, it will be a very small magnet, easily disguised/hidden somewhere.

I think it will fit inside the box OK, especially if I cut off the screw tabs, and use Velcro to adhere it to the side of the box.

While I was at the Sayal store I also picked up a 5/16" round recessed magnetic switch with two attached wires.
Not sure if this is NO, or NC, but it's tiny, and if it needs a magnet to keep it switched on, then I'll epoxy a small rare earth magnet to the inside of my outer radio box cover.
Then all I would have to do to switch off is remove that one outer cover.
No biggy.
Actually I already have a large rare earth magnet holding my outer lid on, exactly under the round Megatech decal, so I may be able to make use of that in this setup.
( Magnet about the size of a quarter glued to the outer lid, large washer glued to the inner lid.)
Depends on the sensitivity of the switch used I guess.

I'll have to do some experimenting here with batteries and light bulbs and switches, etc. to see what works best.

BTW, I have been using that large magnet since the get go, and never had any radio problems, for those of you who may be wondering.

Just have to figure out which wire goes where now!!!

Just rereading your post Gravitar.
That comment about the amperage scale.
Should I be worried?

Isn't that 1/2 an amp?

Is that sufficient when the wind blows hard?

I have no idea what our servos draw.

Or, do the servos draw directly from the battery pack, not through the switch (is that even possible?)

I'm a real newb when it comes to wiring.

John is right, I should not have brought it up. I'm sure with the fast electrics, wire size, current draw and cooling are all to be considered, but here in the sheet world, I am sure it does not apply.

Move on, nothing to see here :-)

Any switch will work fine, but, whats wrong with the original layout? its always good to remove covers from radio boxes, no matter how water tight we THINK they are..condensation happens in all of them, the tighter the box, the worst condensation..the acids, even in the tiny amounts produced by electrical transfer, and motors running, (servos) instead of gassing, and dissipating into the air, attach to the moisture, and attack connections..the green stuff..

So, taking the cover off the radio box is a good thing.

All of my radio boxes are waterproof, a personal thing, most of my boats never have to have a hatch off, to charge, or turn on..BUT, the covers all come off when I'm done for the above reason.
