What push button?

Hello, I just got my spark and have hooked it up to a node server so that the led will blink when a twitter hashtag is tweeted. I am looking for a push button that i can hook up to it? Whats a good one to use? The only ones I have found are 5v?

@jakeboyles, almost any mechanical push button can be used since it simply creates an electrical contact. When you say:

what exactly do you mean by that?
