I have a "dh48s-s" timer that toggles a vacuum pump on/off. I need to toggle the polarity instead but have limited experience using circuits... is this possible? Link to circuit diagram: |

Easiest way is to use a relay. Another much cheaper way is to use an H driver chip, but you need to know much more about the load voltage and current. |
