Wiring Diagram Experts needed

Just did this 2Lo mod and am trying to understand exactly what is going on in the A.D.D. electrically.


In the ADD Actuator Assembly portion, I understand that DM1 and DM2 are running the actual motor to move the ADD into place, but what are the ADD, DL1, and DL2 wires doing? I don't recognize that symbol. Are they sensors that detect whether the ADD is engaged or not?

Thanks

 

Looks to be an internal relay switch, when the other functions are satisfied it looks to trip the switch allowing the ground and completion of circuit. Why it's drawn in a swing gate manner I am not really sure. It looks also as if the switch acts as a bypass to the actual internal relay also.

 

Ok. Thanks I think I understand it now.
