ABSTRACT OF THE DISCLOSURE An improved solenoid wherein the end of the armature within the first coils has a predetermined length of rigid non- magnetizable material secured to it, and a second, electrically energizable coil being energizable in a manner opposite to that of the first coil, being secured to the other end of the length of non-magnetizable material so as to move therewith from a position adjacent the first coil when the arm is in extended position to one space therefrom when the arm is in retracted position. This coil provides magnetic repulsion between the two coils to produce good starting power for the armature when the first coil is energized, as a result of repulsive magnetic forces created between the two coils.
