Abstract
An actuator can include a housing, plunger, core assembly, biasing member, and first and second electromagnets. The housing can have two end poles, and a central pole therebetween. The plunger can be configured for axial translation relative to the housing. The core assembly can move between first and second positions and can be coupled to the plunger. The core assembly can include first and second cores spaced apart by a permanent magnet. The first and second electromagnets can be spaced apart by the central pole and can have opposite polarities. The biasing member can bias the plunger toward a first plunger position when the core assembly is in the first position, and can bias the plunger toward a second plunger position when the core assembly is in the second position.
