Exterior Reset Button

Hi.
I am building a sturdy box for my Arduino and I have to build a new panel mount RESET button ( I have to press it every time I boot max/msp)
I see a RESET pin, and read that the board resets when this pin is brought low. Does this mean a connect a SPST N.O. momentary switch from the pin to ground? I can't afford to test things out to much because i have a show on Sunday and the arduino cannot be fried.

Thanks,
Max ;D

Yes, connecting the reset pin to ground through a SPST normally open switch is what is required.

do i need some kind of pull down resistor? I hear those are for logic but maybe it pertains to this situation as well.

No, you can make the switch connect it directly to ground. Every arduino board should already have a pull-up resistor on reset.
