4720 W/cab diverter switch

[jcalla]

I have a new 4720 w/cab with a diverter switch to toggle between the front & rear SCV. I noticed there are three positions on the switch.
1. on: activated which illuminates a red light: activated,
(rear SCV operational)
2. off, flush with switch housing: deactivated, no light (front SCV operational)
3. off, depressed past flush switch housing: deactivated, no light (front SCV operational)
I checked the operators manual and cannot find any reference to the third position on the switch. Is this a standard switch that has three positions of which only two are used in this circuit , or is there another function of this switch?

if it is a rocker switch the flush is off, most likely

The diverter is capable of two positions either front or rear controlled by the switch which in turn is either off or on. This switch is normally open, which equates to front circuit selected. If you select the rear control and turn off the key momentarily it will revert to front control which is the normal position.
