Abstract
An electromagnetic actuator includes a coil that is selectively energizable by an electric current. The electromagnetic actuator further includes an armature having a outwardly extending prong. The armature is movably disposed with respect to the coil such that when the coil is energized with the electric current, the armature moves in relation to the coil and disposing thereby the prong on a first side of the coil. A flux gatherer is provided to be disposed around a second side of the coil, thereby channeling magnetic flux emanating from the coil back into the armature and prong.
