Abstract
A magnetic armature piece particularly adapted for use with a rotary solenoid includes a pair of high permeability ferro-magnetic rotary poles which are fixed in relationship to each other by relatively thin bridges which connect magnetically neutral regions on the poles so that the required magnetic flux properties of the poles are not lost. Rotary solenoids in which the described magnetic armature piece is employed are more reliable than conventional solenoids because the poles cannot become misaligned during assembly or use.
