Sorry for the questions, just trying to figure it out and the parts suppliers have little to no knowledge and the service manual did not help much either.

Again, many thanks.

Brad:

The B-Pillar microswitch is toggled on and off by the lower part of the B-Pillar, which depresses the little silver lever as the top nears the completely closed position. That causes a signal to be sent to the convertible top double relay, which then sends a signal to the electric motor and that causes the electric motor to reverse direction.

If that little silver lever is bent at an angle sharper than normal, the electric motor will reverse before the convertible top is completely closed.

You can test this theory by pulling the B-Pillar microswitch little lever forward until you hear it click by hooking a little string behind the little silver lever. When you depress the dashboard switch, you will see that the motor (and the V-Levers) then reverse(s) direction.

The little black lever microswitch on top of the electric motor is what sends a signal to the relay to turn off power to the motor, following what Porsche calls an "after-running time" when that black lever is depressed by the clamshell closing down on it.

Here is a photo where you can see the tiny switch that the silver lever presses in:



Here is another photo that shows the microswitch installed and you can see the black metal lower section of the B-Pillar pushing up against the silver lever as the top is nearing its fully closed position (the red arrow is pointing to the silver lever):
