How To Control A 12VDC or 24VDC Motor With Board of Education?

I'm just wondering how I can control a 24VDC/12VDC motor with my microprocessor board from parallax. Since these motors require a lot of amperage, the power the microprocessor board produces will not be enough, so I need to create something like in the attached image.

Basically, if I push a button, that sends a signal to close the switch which completes the circuit. I'm just not sure what electric components I need to do this since it requires like two circuits working together.

    The Nuts and Volts Column #6 is a good starting point on controlling motors, solenoids, etc. with a Stamp. Also look at the StampWorks Manual. The Professional Development Board has what's called an "H-Bridge" on it and the StampWorks Manual discusses this. The Wikipedia has a good article on H-Bridges.

    Start with the Downloads button on the main Parallax webpage. Also, the Resources tab will get you to the Nuts and Volts Columns index.
