An actuator, which in a preferred embodiment, is shown in a wire matrix printer, and includes a magnetic structure having a support member associated therewith. When used in a wire matrix printer, the actuator includes a plurality of output members (in disc form) mounted on said support member for movement between operative and inoperative positions. Each output member has a coil structure thereon, and when the coil structure is energized, the associated output member is moved to the operative position where a printing element on the output member is brought into printing relationship with a platen of the printer.
