Do these things exist, what are they called and where2buy? Sorry for the shitty pic but I'm on my phone so that's all I can do.

Like a small... box. With a small, about a millimeter in diameter pole sticking out of it. When a current is applied it sucks the stick inside it. And when a current is applied again it protrudes out again. No middle ground, just out state and in state.

I mean technically I could build a mechanical contraption that takes input from a stepper motor and a gear or something but I want to know of there's an easy way out.
