one shell, 22 state machines

Between 38% and 72% coil voltage the reading cannot tell you where the contacts are; only the direction it came from can. Hysteresis is the reason the part exists, so the card shows state and input apart and counts the slow, arcing closures inside the band.

Pulled in — the coil is above the 72% pick-up

It stays closed all the way down to 38%, far below the 72% it took to pull in. That gap is deliberate: without it a supply wobbling around the pick-up would chatter the contacts apart in a few hundred operations
