[DG] S3G as backup of SPX-SOL

RE: [DG] S3G as backup of SPX-SOL
It is essential to ensure only one 'pilot can be operated at the same time and so a 3 position switch should be used to isolate them, the centre position being OFF for both systems to ensure there is no possibility of them both being activated at the same time.

The compass and rudder sensors will also need to be isolated as they cannot be 'commoned' between the two systems. We also recommend isolating the solenoids and clutch too because you do not want to back feed power into the back end of the outputs.

Clearly the screen/shield can be left connected, but some form of multipole relay or contactor should be used.
