I have a Bartolini MME triple coil MM replacment pickup that I am installing in a modified J-body. The instructions provided with the pup show a variety of switching options. I would like to wire it up to a switch that allows for single coil,series,paralle. There are diagrams for this wiring, but it doesn't say what type of switch it is. It has a lug pattern like this: - - - - - - - - - - - - Anyone know what type of switch this is? And where I can buy one?
