ABSTRACT:
An actuator assembly includes a first housing portion and a second housing portion coupled to the first housing portion, which together define a housing having an interior. A beam, preferably of one-piece construction, extends from the interior of the housing to the exterior of the housing. A coil, pole piece, and magnet are positioned in the interior of the housing. Energizing the coil causes movement of the beam relative to the housing. The housing portions may be identical. The housing portions may be symmetrical about their edges of coupling.
