z If backward movement is selected, an earth path is created via the switch on an NR wire
z If upwards movement is selected, an earth path is created via the switch on an NB wire
z If downwards movement is selected, an earth path is created via the switch on an NW wire.
The switch is earthed on an NB wire.
