button pad question

Using Arduino General Electronics

Hi all, just had a quick question about this shield:

I have a similar component that I salvaged. I expected it to short when I depress the button and contact is made. Instead, I observe a resistance(cant recall what it was off the top of my head).
Does that seem correct?
Should the button be shorting the circuit?
Will this still work with the arduino as a push button?

Conductive rubber keys have some resistance but as long as it's under 100 kOhm or so you should be fine. The digital inputs have high impedance so it takes very little current to change the pin voltage.
