SETC Operation:

When current is applied to the coil in the stationary magnet body (held in place by an anti-rotation pin), a magnetic field is created which attracts the armature toward the rotor, disengaging the teeth.

When the current is removed, springs push the armature into engagement with the output plate and torque is transmitted.
