help me fine a switch please (picture inside)
 

Hi all

Im looking for a standard impreza dash size switch that has 2 buttons on.

I would like to use it for anti lag and launch control

something like this

In all the years I've spent working on electronics and looking through component catalogues, the only switches I've ever come across that look like the one in your picture were the kind where the top button switches a circuit on and the bottom button switches it off, which is obviously not what you're looking for (unless I've misunderstood, you want the top button to switch LC on or off, and the bottom one to switch AL on or off, but completely separately from one another).

After a quick search now, the closest I've found to what you would need are some switches with a pair of side-by-side rocker controls, like these:

You'd have to widen the cut-out in your dash a bit to fit either of those, but I honestly think it's the best you're going to find off the shelf.

Most people with LC tend to have this activated all the time,as it's set to around 4k RPM then you will never sit there with your foot on the throttle unless you plan on a launch.
So really a single switch would do you for ALS.
Just my opinion tho as I'm sure some do have LC on a switch too.

I wouldn't bother with either mate. Fun for about 5 minutes, kills your cooling system and breaks your transmission.

thank you

the closest i have found so far is this one, but can find where to buy 1 switch from and not in bulk of 1000+

and buy the sound of it, I might only need 1 switch then, the the anti lag?

my car will be getting mapped with the carberry rom

then again, I might need 2 switches, one for anti lag, one for hi/low boost map.

might have a standard looking switch for hi/low boost, and a hidden one for antilag

also what gauge wire would I need ti buy please?

You'd be wasting your time with that switch even if you managed to find a supplier selling them in singles, if you really need to control two separate items. Although it's a dual-pole model, you would still only be able to have either both your AL and LC switched on at the same time, or both of them off.

As for what gauge wiring you'd need, I'd be astonished if 18awg wasn't thick enough. You're talking about pretty minute amounts of power here, to send an electronic signal to the ecu or some other microprocessor, so load really isn't an issue. I personally wouldn't want to use any thinner than that in a car though, just from a material strength point of view (18AWG is about 3mm external diameter, 1mm conductor diameter).

thank you Mark

something like this?

That looks closer to 20awg, but should do the job.
