Hello all, I recently began a small project and ran into some trouble with the electrical components.
I purchased a small 12v reversible DC motor that came with a potentiometer/PWM controller and a 12v power supply. The motor is capable of running in either clockwise or counter clockwise direction depending on how the motor is wired.
My problem comes in when I attempt to insert a DPDT toggle switch to allow for ease of changing direction without having to swap wires. I connected everything, leaving out the switch for now and it all worked as it should, so I know the equipment is not faulty. Here is a diagram of what components I have and what wires are present.

The manufacturer informed me that the switch needs to go on the controller side, not power. Per shipping directions - To run the motor:
In CW rotation, connect motor's green connector to controller's red connector and
motor's red connector to controller's black connector.
In CCW rotation, connect motor's green connector to controller's black connector and
motor's red connector to controller's red connector.
After some research, I learned to change polarity on a switch I needed to add a jumper from 1-6 and 3-4 (see above diagram), so I did that.
From this point on I did quite a bit of reading before coming here and have tested as many circuit combinations as I can think of but I still cannot get it to work as I would like. Being able to change direction with the switch while still maintaining the ability to control the rate of rotation with the potentiometer.
Any help with this would be greatly appreciated as I have run out of ideas and options. Please let me know if you need any additional information.
Thanks!
Robert
