I'm working on developing an Arduino Uno based DAQ system that's somewhat low cost for club racing. Although I'm installing it on my Spec E30 car, I'll definitely post the code and assembly instructions here once I complete it and get it working reliably.

I'm to the point now where I'd like to wire up some switches to the steering wheel that will allow me to cycle through data on an LCD screen and start/stop a datalog. While the easy solution would be to just wire up a push button switch from RadioShack, they stick out quite a bit behind the steering wheel and get in the way of my quick release.

I noticed that a lot of race cars use these types of buttons:


They're much smaller and seem to be more suited towards racing. Does anyone know where I can find these types of switches? I've been searching for a while now but have been unsuccessful.

Additionally, if anyone has a better idea then please let me know.

 

Ask this guy purplecivicturbo , he knows everything, go through his topic if you like electronics

There is a thread on :wiring".... search for it.
Lots of good information there and some knowledgeable guys too.

 

Just look through any major electronics suppliers' catalog. Allied electronics, mouser, etc...

EDIT: Here are over a thousand to look through http://www.alliedelec.com/sensors-sw...lays/switches/

 

This one?

I would love to see some new life in there

 

Thats the one!

 

Im also looking to do something similar with our DC5 build. Gonna share my work in the electronics thread as soon as I make some progress

 

Hey, after digging about for a while a came across this gem ...

http://cgi.ebay.com/ws/eBayISAPI.dll...ht_3103wt_1110

 

Cool.

I found these on the Motec website. http://www.motec.com/sensors/switches2/

 

I haven't figured out where you can actually buy them yet.

 

That looks very similar to a button I found on a motorsports wiring website they wanted $22 each -___-

 

What site was it? I only need a couple so if they're relatively low profile then I think I could stomach the cost.

 

Here is the expensive button - http://motorsportwiringsupply.com/sw...button-switch/

The ebay store I linked to before also has buttons that look similar to what you want. Just search their store for "push button switch"

 

I think I'm going to order these guys. They're close enough to what I need and are pretty cheap. http://www.ebay.com/itm/12-Red-Green...item43a76e217f

 

Nice ill have to choose between those and the ones I posted. Im torn between the 2 styles

 

Actually I went ahead and bought the first set that you posted since I'm thinking that they might be easier to push with gloves on. The other ones don't protrude and might be hard to trigger with my thumb.

 

OP, what's new with your project?

I've recently gotten bit by the Arduino bug and I thought of this thread.

 

You guys should check out what some of the serious sim racing guys do. They use the same types of real wheels we do in our cars.
