So what's the difference between a Tact switch and a normally open switch? The Tact one seems to be also a 'normally open switch'.

Also, what kind of switch should I be look for if I want it to stay closed when pressed, and open when pressed once more?

    That would be a Push-On/Push-Off switch.· Jameco has a nice selection of them.·· www.jameco.com

    Ok, novice question....

    What is the difference between a push button and a tact switch? They both appear to be pushbutton switches. Is "tact" short for "tactile", as in the switch has a snappier tactile feeling to it?

    Jim,
    The term tactile in reference to a pushbutton refers to the tactile feedback. It will have a "click" feel to it so you know that it has been pressed without looking. Normally open or normally closed is a description of the electrical function of the switch and is independent of the tactile feedback.
    Hope this helps.

    Ok, I get the tactile part. I thought that's what was implied by the name, but didn't want to assume.

    Bugg, what do you mean by a tab? Do you mean the internal construction within the switch?

    Thanks,
    Jim
