tilt sensor switches: where to buy this one?

Anyone knows the identification name of this tilt switch/sensor? http://yfrog.com/c9tiltsensorj

That's the one which comes with the arduino base workshop kit I have.

The kit comes with just 2 of them and I need another one.

I'm looking for online sellers/shops, possibly in Italy or Europe. I've not been able to find this one in local shops (Torino, Italy).

Any suggestion?

Thanks,

Fabio Varesano
