I'm not exactly sure what you're trying to do. You can change positive to negative and vice versa with a double pole double throw (DPDT) switch.

If you look at the bottom of a DPDT switch, there will be 6 pins (pins are numbers 1-6 in the "drawing" below).

--------
| 1 4 |
| 2 5 |
| 3 6 |
--------

To change the polarity make pin 1 the positive from the battery and pin 3 the negative from the battery. Then get two wires and wire pin 1 to pin 6. Also wire pin 3 to pin 4. Your output pins will be pins 2 and 5. Beyond that, I'm not sure what you're doing so I can't really recommend anything.
