There is nothing I have tell before I go about on this madcap search. The problem is that I'm only 12 and searching for a device (or a circuit) which changes, or swaps, polarities, every time the switch (a switch made from a phototransistor and a resistor, in essence, getting activated wirelessly) is on. In other words, the motor (brushed) to which it will be connected will spin in one direction, and will begin to spin in the opposite direction once the switch is switched on.
