Hi Brad
It would be helpful if you could be alot more specific. For example is it a single phase motor or three phase motor you are controlling.Multi speed?? AC or DC etc. Also what exactly do you mean by

"reverse a drum switch" .

<font size="2" face="Verdana, Helvetica, sans-serif">Do you want what is now forward on the drum switch to be reverse??
Try to provide as much info as possible as this will make it easier for anyone here to provide a quality answer.

I will have to assume that what you want to do is this: If the motor spins ccw in forward and cw in reverse you want to make it spin cw in forward and ccw in reverse.
This is quite easy to do either at the motor connections or at the drum controller.

At the motor connections just switch any two phases,OR (Do not do both)
At the drum controller find the three phases that "feed" the controller (line 1,2 & 3)and switch any two phases.

Brad,
Not sure exactly what you want.

Here is a sketch of a basic Drum Switch connected to reverse a three phase motor.
Note that this is only one of many different drum switch configurations.

Make sure that the switch you are using is approved for 600 volt use.
