How do I design a board that would switch the direction of the current on a switch of a button?

Question

I need to design a board that will reverse the direction of the current when there a switch is pressed, and the second switch signal would reverse it again. Please tell me the name of such a layout (if it exist), or explains how it works.

Answer 1

look at a Flip Flop circuit. If you need any e-mail me. All you would need is a Flip Flop circuit and a DP/SP relay. Double Pole Single Throw relay.
A circuit like this will say change the direction of a DC fan with a push of a button.

Answer 2

use a single throw double pole switch
