Claim 14:
15. A solenoid, comprising:
a wire coil;
an armature including a permanent magnet, wherein the armature is moveable between two stable positions in response to selective energization of the wire coil; and
two magnetic dampers, each of the two magnetic dampers is arranged along a travel path of the armature at a respective one of the two stable positions,
wherein the two magnetic dampers are configured to generate a magnetic damping force in response to relative movement between the armature and at least one of the two magnetic dampers, and
wherein a direction of the magnetic damping force is opposite to a movement direction of the armature to restrict overshoot when the armature travels to one of the two stable positions.
