Abstract
The switch comprises two contactors movable along two rows of four contacts, to an "OFF" position in which each contactor bridges the second and third contacts in each row, a first "ON" position in which each contactor bridges the first and third contacts in each row, and a second "ON" position in which each contactor bridges the second and fourth contacts in each row. An inner crossover conductor extends between the first contact in the first row and the fourth contact in the second row and is disposed between the first and second rows. A second crossover conductor is on the outer side of the contact supporting board and is connected between the second contact in the first row and the third contact in the second row. A flat Z-shaped insulating member is held captive between the board and the inner crossover conductor.
