Hi im just wondering if its possible and easy to make a aircraft style switch (like the one in the link below) to be a battery isolator switch??

maybe, you would have to get a heavy duty one as a normal switch would burn out because of the high power going through it.

A bit like this http://www.demon-twe...aign=Motorsport ??
Or would using it to maybe just isolate the starter work??

Still not rated high enough, to be safe 65amp minimum would be the rating.

What are you try to achieve? Is this for security or to stop the battery going flat??

[Artful Dodger]

yup. what rukus said. would need to be a biggun if its going to supply the main feed battery cable. that would work if you were running it for ignition. mine turns on all of the engine electronics such as the solenoid ect.

MiniclubmanGT;

Can you send me a PM/ post on here telling me how you wired the switch?

I really want a switch that starts the engine without me having to turn the ignition key forwards first. Or is that the only way to do it?

Cheers,

Simon.

Its for security really so i wouldn't mind if some of the electrics still worked as long as the engine electrics switched off when i flicked the switch. And it looks much sleeker so will fit into the dash nicely and be harder to tell that it controlled weather the car started or not rather than the big red key'd ones

cheers for all your help so far

to use the switch to cut power to the engine put the switch in series with a wire coming from the ignition barrel. the sprung position is the trigger wire for the starter solenoid the one before it gives power to the coil and other bits. this wire shouldnt pull more than 25 amps. the switch you have chosen will be able to cope with this amount of current. without power going to the coil the car wont start, even if you try to bump it.
