Abstract
A magnetic actuator particularly suitable to be arranged in a circular array to form a wire matrix printhead for mosaic, or dot, matrix printing. Each such magnetic actuator of three poles being (1) and 'E'-shaped core defining three magnetic poles which is substantially thin in the thickness of the 'E', which is that direction circumferentially along a circular array of such magnetic actuators, (2) a single coil wound around the center magnetic pole of such 'E'-shaped core, and (3) an armature striding over all three magnetic poles. The armature is maintained at its pivot point by an O-ring which creates no moment of force to the striding of the armature. The 'E'-shaped core may be comprised of laminated, or of solid, magnetic material and may further be structurally in common with the cores of other ones of the magnetic actuators as are arranged in the circular array.
