An electromagnetic linearly indexing actuator in which a shaft is mounted for linear motion in the direction of its axis. A pair of electromagnetic stator assemblies are carried in fixed position coaxially spaced from each other in the direction of the shaft axis. Each stator assembly has an associated armature which is slidably carried by the shaft, and a spring for urging each armature away from its associated stator. A latch is pivotally mounted at one end to each armature eccentrically of the shaft axis and has a central aperture which embraces the shaft. The stator assemblies are sequentially and alternately energized, so that the latches alternately grip and move the shaft during motion of the associated armatures. The shaft is returned to its initial position by a return spring, or by an opposing pair of armature and stator assemblies.
