Abstract
A solenoid includes a base formed with an external taper and an adjacent hub sleeve also formed with an external taper, the base and hub being joined by an alignment piece of non-magnetic material formed with a pair of internal tapers which are proportioned to mate with the external tapers of the hub and the base. The alignment insert assures and maintains a predetermined concentric coaxial alignment of the hub and base with respect to a common movable armature.
