The modification will require a 7 pole 3 throw band switch. I bought an 8 pole 5 throw switch on eBay (I have since found a 9P3T that would be a better choice). The new switch will need some modification.

I drilled and tapped the front plate and installed a stop screw to limit the travel to three positions.

The shaft diameter is 6mm and about 1/2 inch long and will need an extension.
