A two-way motor is designed to run in either forward or reverse as needed. Commonly found in automobiles with automatic power windows, these motors are usually controlled by a double pole double throw switch. This allows a single switch to control whether the motor goes in forward or reverse. These motors can also be used for reversible pumps and winches.

Instructions

  1. 1

    Place the battery on the work table. To the right of it, place the DPDT switch. To the right of the switch, place the motor. Cut one black wire and one red wire 2 feet in length. Strip 1/2 inch of insulation off of each end of each wire.

  2. 2

    Label the terminal pins on the DPDT switch. The two pins connected to the lever will be pin "A" and pin "B." The pin to the left of pin "A" will be pin "C," and the pin below pin "C" will be pin "D." The pin to the right of pin "A" will be pin "E," and the pin below pin "E" will be pin "F."

  3. 3

    Connect one end of the red wire to the positive terminal of the 12-volt battery. Connect the second of the red wire to pin "A" of the DPDT switch. Then, connect one end of the black wire to the negative terminal of the battery and the other end to pin "B" of the DPDT switch.

  4. 4

    Cut two 6-inch pieces of black and red wire. Strip 1/2 inch of insulation off of the end of each wire. Connect the red wire to pins "E" and "D," and connect the black wire to pins "F" and "C."

  5. 5

    Cut two more black and red wires to run to the motor. Strip the ends of each wire. Connect one end of the red wire to the positive terminal of the motor, and connect the other end to pin "F." Connect one end of the black wire to pin "F," and connect the other end to the negative terminal of the motor.

  6. 6

    Swing the DPDT switch to the left and the motor will run in one direction. Swing it to the right and it will reverse directions.
