can anyone recommend a source for monentary switches? preferably somthing a little better than what i'm currently using, radio shack buttons (http://www.radioshack.com/product/index.jsp?productId=2062545&cp=&kw=momentary+switches&parentPage=search) and they're not hold up well in my race car. The buttons are used to power on/off an in-car cam and start recording. The in-car cam setup doesn't tie into the car, it's a complete separate systems.

I bought really good guitar pedal switches here. Nice breadboards as well.
Think Inside the box first and if that doesn't work..
Re-arrange what's inside the box then...
Think outside the BOX!

It is hard to recommend without knowing how much current your switching.
Try Digikey (www.digikey.com (http://www.digikey.com)) They have a good selection of switches.
Automation Direct has some great industrial Push Button switches. Long life, hard to kill, replacable contacts and a good price.

current is not a problem, everything is power off of 2 AA batteries. it's more about the mechanical durability of the switch in a harsh environment of dirt track racing.

If the problem you envision is that of dirt infiltration into the switch (regardless of the exact type which you don't mention), you may want to consider using a rubber boot over the switch. That will make it dirt, dust, and weather resistant.

If you can afford the space, the Automation direct Push buttons work good in a harsh environment.
they need a 22 mm hole, and about 3-4 inches behind the panel.
You also experience high vibtastion levels.
I would Loctite the switch components.
It may be hard to remove, but it will not come apart in turn 3 either.
