a housing;
a pole piece;
an end plate formed with or coupled to the housing;
a wire coil arranged within the housing;
a permanent magnet arranged between the pole piece and the end plate;
an armature configured to selectively move between a first position and a second position in response to a current applied to the wire coil; and
a pin coupled to the armature, wherein the pole piece includes a bearing protrusion that extends axially from the end plate and that includes a bearing surface that slidably receives the pin,
wherein the pole piece includes a thin-walled portion that extends through the permanent magnet and is dimensioned so that magnetic flux generated by the permanent magnet saturates in the thin-walled portion.
