Step 2: Wiring the switch

Wiring for this switch is deadly simple.

To make my instructions a little more easy to follow, hold your switch in such a way that you are looking at the pins and they are arranged 2 pins wide and three pins tall. Imagine that the pins are numbered as below:

1 4
2 5
3 6

Begin by connecting pins 3 and 6 directly. The shortest piece of wire you can use will be best. You will need no other access to these two pins.

You will need to connect two wires to each of pins 1 and 4. These pins will be your two power supply wires, as well as one wire from EACH of your motors. As this switch WILL NOT change polarities, make sure that your positive wire from one motor (we will call this one Motor "A") is connected to the positive power source wire, and pin 1. Connect the negative from your other motor (Motor "B") as well as the negative from your power source is connected to pin 4.

This is the tricky part. You now should have only 2 free wires, one from each motor. These wires will get crossed in this step. This is intentional. Connect the wire from Motor "A" to pin 5, (not 2, like you would expect). Connect the wire from Motor "B" to pin 2 (not 5).

In my other instructable, I note here that there are many different combinations for the connections to that switch, however, there are some things that you MUST be careful about in this switch. You CANNOT connect your power source to pins 2 and 5 in this switch. The motors will be wired in series in one position, however the switch will cause a short in the other position.

Will this work on a Jazz bass, to change the pickup configuration? I was going to put in a push-pull pot for this, but have several of this type switch on hand. Thanks for the info. BennyB

Before I answer that, let me point out that I have absolutely no idea about guitars. That being said, this switch will allow you to have the pickups in series or in parallel to each other. I have no idea if that is something you would or wouldn't want to do with the pickups on a guitar. Since no power is put into the guitar from the amplifier, I don't THINK anything can be damaged by wiring the pickups improperly, so I would say try it, and let me know!
I believe that will do what I want. It just alters the sound output of the pickups. Thanks. BB

I am sorry, but I do not have a camera with which to take any pictures. The few pictures I have were taken by a friend. It does not matter which pin is pin 1 in most switches. It MIGHT matter if you have a lighted switch, in which case it will matter where you connect the positive and there may or may not be an EXTRA pin for the ground. Follow the instructions that came with your switch if it is a lighted switch. Thank You for your comments! Mike, at DC.

Does it matter how you hold it? I mean can you hold it the opposite way and still have the same meaning? Also how do you tell which one is pin 1?
Can you also add a picture of your DPDT slide switch after you have finished soldering as I am a little confused with how to connect it.
