On these Tri-State-Switches the pins of the back row can be switched from home position (0) to the left (+) or right (-) front row pin. That gives you three positions per pole. The benefit of three positions per pole is when it comes to devices with limited space and higher numbers of codes are needed, tri-state switches will offer 3n different codes in the same space where a standard DIP-Switch will only have 2n codes.
