Using the eight diodes to drop V to 12 V or so, I assume, assuming a drop of .7 V for each? Probably a regulator, cap and resistor would be better and easier than the eight diodes?
Polorotor = Mechanical Servo Motor
This circuit would not control a Polorotor, but it would send 13 or 18Vdc to select either Horizontal or vertical on a LNBF.
What is the purpose of using this manual polarity switch instead of just using the STB to provide the 13/18 voltage?

I think this could be handy for some older commercial equipment, but not for any consumer type STB made in the last 10 years.
