What Is This Transistor Circuit For?

[pwdrive]

The wire from the NO of SW802 has no junction spot to connect it with the common wire to the brake and pinch roller solenoids. They are just shown crossing.
SW802 is shown rather close to the wire to the solenoids however on zooming the viewer it shows that there is a mistake in your diagram in post#15.

Cheers for that , it looked like a dot at first....damned copies.

I'll do another schematic, showing the other switches this time.
