SETB Operation:

When current is applied to the coil in the magnet body, a magnetic field is created which attracts the armature toward the magnet body, disengaging the teeth, and allowing the load attached to the output plate to rotate freely.

When the current is removed, springs push the armature teeth into engagement with the output plate teeth and the load is held.
