ABSTRACT:
A solenoid having a coil that includes the usual bobbin or spool, winding and armature in combination with a flux collector that is uniquely formed and associated with the coil bobbin and with the armature to maintain essentially precise concentricity between the flux collector and the armature and the intervening air gap of a uniform minimum width dimension so as to minimize the size of the coil and loss of armature power in use while at the same time assuring an adequate and reliable operating force in the armature.
