      Hooking Up The DPDT Center-Off Switch

      Obviously you don't want to have to rewire your motor every time to turn it off or change directions. We're going to let the switch do that. Inside the switch there are metal strips that either connect the wires or disconnect them, as the lever is flipped back and forth.

      Wiring and toggle switch.
      Here are the wire assignments:

      • Yellow: Positive terminal of the motor.
      • Blue: Negative terminal of the motor.
      • White: Positive terminal of the battery.
      • Black: Negative terminal of the battery.


      Solder the white (power positive) wires to the DPDT switch.
      1. Connect the white wire (positive power) to the DPDT switch as shown above. You'll need one long piece of wire coming from the battery to the first switch terminal. And, you'll need a smaller piece of wire coming from the first switch terminal to the opposite terminal as shown.

      Solder the black (power negative) wires to the DPDT switch.
      2. Connect the black wire (negative power) to the DPDT switch as shown above. You'll need one long piece of wire coming from the battery to the lower switch terminal. And, you'll need a smaller piece of wire coming from the lower switch terminal to the opposite terminal as shown.

      Solder the yellow and blue motor wires to the DPDT switch.
      3. Connect the yellow and blue wires from the motor to the center terminals of the DPDT switch as shown above.
      4. Connect the yellow and blue wires to the motor terminals.
      5. Make sure the switch is in the center (off) position, before connecting the battery.
      6. Connect the white and black wires to the battery.
      Controlling the Bidirectional Motor Switch

      Let's step through what happens when you flip the switch to the top, center, and bottom...

      Lack of connections in a DPDT switch, resulting in a turned-off motor.
      When the switch lever is in the middle position, the motor is off because the metal inside the switch is not connecting the wires from the middle terminals (the motor) to any of the outer terminals (the power source). This is the same as if you simply disconnected the wires to the battery. Nothing will happen. No power is being used.

      Connections in a DPDT switch, resulting in a motor going forward.
      When the switch lever is in the top position, the motor rotates forward. If your motor rotates in the opposite direction than you expected or wanted, simply reorient the switch in your hand so that lever is facing the bottom, and then toggle the lever to the top. Alternatively, you could swap the wires on either the battery terminals or the motor terminals.
      Inside the switch, the lever has pushed metal strips such that the motor wires on the middle terminal are electrically connected to one pair of the outer terminals leading to the battery. The term "double pole" refers to that fact that this switch has a pair of terminals that it connects or disconnects at the same time. If we only needed a single wire to be connected or disconnected, we could use a single pole (SP) switch.

      Connections in a DPDT switch resulting in a motor going backward.
      When the switch lever is in the bottom position, the motor rotates backward.
      Inside the switch, the lever has pushed metal strips such that the motor wires on the middle terminal are electrically connected to the other pair of the outer terminals leading to the battery. Notice that the black and white battery wires are on opposite sides on the top and bottom switch terminals. That's why the motor rotates in the opposite direction.
      The term "double throw" refers to that fact that this switch can be thrown to the top and thrown to the bottom (two different throws). If we only needed the motor to go forward or turn off, we could use a single throw (ST) switch.
      Trouble Shooting

      If your motor doesn't operate correctly, double check that the wires go to the correct switch terminals. Also, make sure the wiring isn't loose or broken. Use a magnifying glass to make sure not even a tiny strand of wire is accidentally touching another wire or terminal.
      Alternative Motor Control With Automatic Limit Stops

      Being able to control a motor directly is useful. But, sometimes you won't be paying attention and the item connected to the motor will crash into a barrier or otherwise exceed its maximum position.
      It would be nice to add a couple of additional switches to automatically stop the motor when it has gone too far, but still allow the operator to return the motor to an allowed position.

      Wiring diagram of a DPDT connected motor plus two snap-action switches for user control with limit stops.
      The wiring diagram above is similar to the ones shown earlier. Two additional switches have been inserted. One switch connects (or disconnects) the white wire on the bottom terminal. The other switch connects (or disconnects) the black wire on the top terminal.
      Snap action switches have been put to good use in my Flip-Flop robot. If you're not familiar with those types of switches, take a quick look at the pictures and watch the video.
      The idea is that each snap-action switch is wired such that their respective wire is normally connected (NC) just as it was in earlier diagrams. This allows the user's DPDT switch to operate as usual.
      However, when something presses against the snap-action switch, it disconnects the wire, cutting off power in that direction only. If the user throws the lever into the opposite direction, the other snap-action switch is not being pressed against, and so it allows the motor to reverse.
      If you mounted a motorized device on a linear (straight) track and placed each snap-action switch on opposite ends of the track, you could throw the switch in one direction and the device would automatically stop when it reached the end of the track. You could then throw the switch in the opposition direction, and the device would proceed to the other end of the track before stopping.
      Similarly, you could add a pin or arm to a disc, which would press against a snap-action switch when the motor shaft rotated to the desired angle.

      How to Wire a 6-Pin Toggle Switch

      A six-pin toggle switch is also called a double-pole double-throw, or DPDT, switch. The term double-throw means that you can connect two separate devices, and each switch position selects one of the two devices. The term double-pole generally means that two pins/terminals exist for each connection point. The DPDT switch has two basic forms: On-On and On-Off-On. An On-On DPDT switch only has two positions. An On-Off-On DPDT switch is similar to On-On, but it has a center position that is isolated from the other two positions. Testing an On-On, DPDT toggle switch with a multimeter is one way to understand how you can wire the six terminals.

      <li class="step"> 1 Connect one alligator clip to each wire of the 9-volt battery clip. If the toggle switch has screw terminals, skip this step. If necessary, use wire strippers to expose enough bare wire on the two wires of the battery clip. Wrap the bare wire around the alligator-clip screw clockwise, and use a screwdriver to tighten each screw.


      <li class="step"> 2 Plug the red multimeter probe into the "Volts" port on the multimeter. Plug the black multimeter probe into the "Com" or "Ground" port. Set the multimeter to measure voltage, and place the level on 20V. Refer to your multimeter manual for more information.


      <li class="step"> 3 Connect the red multimeter probe to a terminal on one end of the toggle switch. Use the probe clip to attach it. Move the lever, or toggle, part of the switch so it is at that end terminal. This will be the "A" position of the toggle switch.


      <li class="step"> 4 Connect the black multimeter probe to the other terminal in the A position of the toggle switch. Use the probe clip to attach it.


      <li class="step"> 5 Connect the positive/red wire of the battery clip to the middle terminal of the toggle switch, near the red multimeter probe. Use the alligator clip for the connection. If the toggle switch has screw terminals, connect the red wire of the battery clip by wrapping the bare wire around the screw clockwise. Use wire strippers to expose enough bare wire, and use a screwdriver to tighten the screw.


      <li class="step"> 6 Connect the negative/black wire of the battery clip to the middle terminal of the toggle switch, near the black multimeter probe. If the toggle switch has screw terminals, wrap the black wire around the screw and tighten with a screwdriver.


      <li class="step"> 7 Attach the 9-volt battery to the clip, and turn on the multimeter. Keep the toggle in the A position.


      <li class="step"> 8 Observe the multimeter display. It should read around 9V. Move the toggle to the other end of the switch. This will be the "B" position. Observe the multimeter display. It should read 0V.


      <li class="step"> 9 Move the red multimeter lead to the terminal in the B position of the toggle switch. Connect it to the terminal near the red battery wire. Move the black multimeter lead to the terminal in the B position, near the black battery wire.


      <li class="step"> 10 Keep the toggle in the B position, and observe the multimeter display. It should read around 9V. Move the toggle back to the A position. The multimeter should now read 0V
