F 350 4X4 won't come out of 4WD Low

I received a recomendation earlier on this forum and need more. I believe that I have found the problem. I removed the manual Shift on the Fly switch and believe that it is not functioning correctly. With the plug removed from the back regardless of the manual switch position there is continuity between the two outside posts and the two outside posts. It is as if the two center posts are a circuit and two outside posts are a circuit. Regardless of where I move the switch it remains the same.

I feel that unless there is an electronic component int the switch that ativates when the switch is powered this switch is not functioning as rotation changes nothing. I have taken it apart and find nothing obviously wrong. I don't dare simply jumper the wire side of the plug as there are resistors in the switch that must drop the voltage. Jumpering possibly could pop something in the computer.

I simply do not want to spend $44.00 for a switch and find my thinking screwed up and still can't get it out of 4WD. Any help will be appreciated.
