Three months later I have a circuit that works in the manner listed below. This allows the window to function automatically, plus still gives the option of stopping the window anywhere in its travel. Two prototype units have been installed and tested in vehicles for over a year now without any problems. How the unit works Automatic operation Press switch in the up direction and release. The window will travel up until it is fully closed.
Press switch in down direction and release.
The window will travel down until it is fully open. When window is travelling up press the switch down momentarily. The window will stop where it is When window is travelling down press the switch in the up direction momentarily. The window will stop where it is. If the window is obstructed during its travel it will stop when stalled as if it had reached the end of its travel, this is a safety feature that operates if you get an arm or hand caught etc.
