ABSTRACT:
A rotary shutter actuator comprising a retainer, a rotatable member, a plurality of shutters, and a dial. The rotatable member is supported by the retainer, and the plurality of shutters are swivelably coupled to the retainer. The dial has an opening and is operably connected to each of the shutters and the rotatable member. Thus, as the dial is rotated, the shutters move to and from a fully open and closed position. The dial also causes the rotatable member to rotate with respect to the retainer.
