Schematic for power window switch?

[TeeJayHoward]

The FSM doesn't appear to show the internal workings of the power window switch itself. Does anyone have a circuit diagram for the switch? (And, while I'm at it, for the motor?)

Note that I am NOT looking for the below photo:


I want something that looks more like this:


And yes, I know that it's a far more complex component. What I want to know is, how does it work? Where is the limit switch located - In the motor or in the switch? Does the motor handle auto up/down functionality, or is it in the switch? Does the motor have complicated enough circuitry that it's pulling in a data feed a la LIN (or even CAN) bus, or is it some sort of dual half-bridge setup?

And, for no real reason other than it's nearly impossible to find pictures of the window switch circuitry online, here's a few pics of the inside of one of the switches:




edit: Oh, and anyone know what SN1/SN2 stands for in the FSM diagram?

Best of luck on that. I'm interested if you will get any hits on that. Typically, as it's not a serviceable component, they don't release information on how it's manufactured.
