In a rotary solenoid employing a hinged armature, an output shaft and converter means including a ball located between oppositely inclined cam surfaces in the armature and the output shaft, for converting arcuate movement of the armature to rotary movement of the shaft upon energization of the solenoid, the improvement wherein the various cams in the output shaft are double cams of different length and opposite inclination joined at their deep end. Preferably the output shaft employs two pairs of such double cams arranged in diametrically opposed locations on the shaft, and including for example, a 90 DEG RH cam joined to a 15 DEG LH cam and also a 90 DEG LH cam joined to a 15 DEG RH cam. The armature can have either a single cam or a double cam comprising two cams of different length and opposite inclination. Depending on the direction of the torsion return spring, the solenoid can be set up for either left hand or right hand operation. Further, the use of the double cams according to the present invention reduces the tooling and stocking requirements of the manufacturer.
