Gentlefolk...
I should know how this works, but my memory fails me...
The 777 RUN/CUTOFF relays are dual coil and appear to have two energised states

If there is no "neutral"/normally open position, are the relays magnetically latched in the last position with permanent magnets ... or are they rotary-type relays which latch in position.. or none of the above?
Thank you!
